Fight for Conservation

 

Georgia aster (Symphyotrichum georgianum S3)

Once nature is no longer protected, it is hard or – in some cases – impossible to get back. As environmental stewards process where we are at this moment in America, it’s time to double down. Vital lands and resources are once again at risk, and it’s up to us to protect them. For a preview of the kinds of changes waiting ahead, the folks at Alt National Park shared this impact list compiled from 4 years ago.

Seek out the causes that are important to you: local lands, state & national parks, tribal lands, ocean health, endangered organisms. Join groups that monitor environmental issues so that you have enough notice to take action when needed. In addition to the ones mentioned in the linked article (Earthjustice, Center for Biological Diversity, Sierra Club, National Resources Defense Council), I would also mention Southern Environmental Law Center and The Nature Conservancy.

Donate your time, your talents, and money if you are able. As always, convince others that these issues are important. Remember, there is no Planet B and birds, insects, and animals have only us to speak for them. Let’s get busy.

This is How a Robin Drinks (the book)

 

The author of this new book is absolutely a kindred spirit for me. This is a collection of urban nature essays that remind you that nature is right outside our door. I first heard of Jo Brichetto’s Sidewalk Nature blog from my friend Gail in Nashville, TN. Subtitled “Everyday wonders in everyday habitat loss,” my own experiences in Georgia can validate what she is experiencing just 4 hours north of me.

The stories of her exploring nature at baseball fields while her child played (I mean, you might as well, right?); shouting out findings to anyone with her (“Coopers hawk!”); getting excited that someone was taking a picture of a hackberry (“That man sees that tree!”); all of these are my same types of ups and downs (he didn’t see that tree after all) that come with living in urban nature.

This collection of essays is grouped by season but they are perfect for anytime. If you’re a Southerner, you’ll enjoy her easy conversational style, sprinkled with the expressions we all grew up with (and if not, you’ll be amused by them at least). Most importantly, these are stories of someone living with nature every day: in every walk and car ride; with every sound, smell, and wayward leaf; and sharing it as much as possible with those who will listen … and learn.

In the catalpa story in the spring section, we discover someone did listen (and those rewards keep us all going). I’ll let you read about that yourself but leave you with her delightful description of the flowers: 

“Catalpa blooms such blooms. Big, frilly, and so exotic I’d never buy them if they were in a flower shop, which they aren’t, and if I bought cut flowers, which I don’t. They look like some made-up tropical thing on a sunscreen bottle, but catalpa is a native tree. They are as Nashville as Osage orange or black locust, and nearly as redneck as a hackberry.”

American Weeds in Japan

 

I visited Japan earlier this month and was surprised to spot several of our native plants behaving badly in unmanaged spaces such as along railroad tracks and on the edges of fields. The first one I noticed was mare’s tail (Erigeron canadensis syn. Conyza canadensis), an annual plant that was growing in cracks and untended sidewalk plots near our hotel in Tokyo. It was amusing to see this little weed work its way into the urban environment.

Solidago altissima

Erigeron canadensis

A trip to Mt. Fuji took us by train through rural areas and revealed a far more serious invasive: tall goldenrod (Solidago altissima). The spread of this plant in large groups and across large areas was disturbing (no pun intended). This website explains that it was intentionally brought in as an ornamental and for honeybee support around 1900 and tends to be its most aggressive in untended areas.

Other invasive American plants can be found on this list, including giant and common ragweed (Ambrosia), broomsedge (Andropogon), tickseed (Bidens), black locust (Robinia pseudoacacia), pokeweed (Phytolacca americana), and ticktrefoil (Desmodium). I personally saw all these things just in our short visit and limited travels.

Giant ragweed

Pokeweed

I saw other American natives being used deliberately as ornamentals such as black-eyed Susans (Rudbeckia) and scarlet hibiscus (Hibiscus coccineus). A visit to an ornamental garden in the Mt Fuji area found plants like sourwood (Oxydendrum arboreum), oakleaf hydrangea (Hydrangea quercifolia), and muhly grass (Muhlenbergia capillaris).

Other exotic plants that are invasive for us were also invasive for them, of course, but I was also particularly on the lookout for some of their native plants that are invasive to us—kudzu and Japanese knotweed, for example—and I did see them growing rampantly in untended areas, especially along railways. I also was curious about finding their native Jorō spiders and we did, particularly in the more natural areas around Mt Fuji. The webs were big and communal, just like here.

Kitaguchi Hongu Fuji Sengen Shrine 

My trip would not have been complete without admiring some of their beautiful Japanese maples both in gardens and in the wild. 

We also found lots of Japanese cedar (Cryptomeria japonica), both in the wild and at temples and shrines (these enormous trees are sometimes called Japanese Temple Cedars and are quite revered). Azaleas were not blooming but they were frequently used as urban street shrubs, and of course Japanese cherry trees were everywhere (again, not blooming).

October 2024 Moment in Nature

While autumn temperatures may go up and down, confusing humans as to whether it's "fall fall" or just "false fall," the plants know what to do. Late season native fruits are ripening and one that I always look out for is our native persimmon (Diospyros virginiana). 

I found this one on a tree near my neighborhood, same as every year, and the comfort of natural rhythms is very soothing in an ever-changing world.

While this particular discovery is my #momentinnature for this month, I will share with you a previous instance, full of the mischief of the upcoming holiday.

Strange Fruit: Oak Galls

Native oaks (Quercus spp.) are keystone species for insects and the ecosystems in Georgia. Over 550 species of Lepidoptera (butterflies and moths) use them as a host plant, and their larvae (caterpillars) are important sources of food for birds and other predators. Other insects rely on oaks too and sometimes their use of oaks creates growths that might appear to be flowers or fruit. These growths are the plants’ response to the egg-laying activities of small wasps or midges. According to this article, there are around 800 different types of galls to be found on oaks in the US/Mexico/Canada areas.

I have seen a number of different types of oak galls in my area and I have pictures of some but not all of them. I will supplement this post with photos from others (each image is credited unless it is mine). Perhaps the most noticeable of the oak galls in my area is the Wool Sower Gall. When it is at its best, it is a fluffy white ball with red spots created at leaf buds. Identification groups get dozens of requests to identify “this tree” when the galls are prolific.

Some galls are leaf galls – meaning the tiny insects lay eggs in the leaf – while others are stem galls. A friend of mine recently found an excellent example of a mid-rib type of gall, perhaps the Clustered Midrib Gall Wasp (Andricus dimorphus).

Mid-rib leaf gall (D. Lane photo)

Another fairly noticeable type is the Oak Apple Gall. By the time most people find it on the ground where it fell, it is a lightweight, papery husk.

One year there was an abundance small, hard red galls that look like aborted fruits. The identification groups in Georgia got numerous questions on what tree produced these.

In researching for this article, I found great information on an Ohio website. It contains a number of articles on the different types of oak galls. It is one of the few sites that presents information without trying to give guidance on how to kill them. 

Most galls seem harmless to the tree, but some can cause minor twig damage. None are fatal to the host plant. The diversity of shapes and sizing is incredible. Look out for galls on your oak trees and be amazed at what nature can do.

A Collection of October Posts

 

This blog is seasonal. Every week the topic has something to do with what’s happening: in the yard, in the season, even what’s happening with me. For those of you who haven’t been following since day 1 (Mapleleaf viburnum: October 14, 2010), you can still enjoy the posts by scrolling through the archives on the right side of the blog.

I find it entertaining to occasionally go back and see what I posted about in the same season, even in the same month. October can be such a good month for being outdoors, enjoying an abundance of fall flowers, and delighting in the beginning of the fall color season. Here are a few of my favorite October posts over the last few years.

October is a great time to fall in love with our native asters. I have posted about them several times over the years, highlighting the different species in my area (with more in this post too) as well as tried to demystify the species of small white ones. Not only are asters number two on the list of keystone perennials, but they also are huge sources of late season nectar and pollen for native bees and butterflies. Add more to your garden!

It’s a good time to evaluate or appreciate what you have in the home garden. Is your garden supporting the fall migration of butterflies like the Monarch? This post highlights some fall nectar plants (spoiler alert, it mentions asters as well as other plants). This earlier post is similar but you might find it inspiring.

Other posts that seek to inspire you include this one with the Lorax to remind us that we have the power to make change in a positive direction. This next one specifically talks about including host plants for our native butterflies. It has a printable chart. This third post is your reminder to be diverse in the garden, not just for host plants but for nectar too.

If you’re just done with flowers and want to bask in the glow of the trees, here are two posts for you. One is about planting native trees that give you double duty or the more recent “Get a Tree That Does More.” Dreaming about driving up to the mountains for leaf-watching? Bring It Home: Fall Color gives you ideas for having good fall color in your own yard.

 

Talk to Your Neighbors about Native Plants

As we learn more about the benefits of using native plants, it is natural to want to spread that information to neighbors, friends, and family about why it matters. What I’ve found is that people are surprisingly open to learning more but usually appreciate help in making changes. Here are some ideas for spreading the native plant message among friends. 

1. Introduce the idea: You might play off areas of interest like birds (“I noticed you like to feed the birds”) and butterflies (“I love butterflies but I haven’t seen many this year, have you?”) and then talk about how native plants support them better. Explain about how you learned that diminishing landscapes with native plants have contributed to declines in birds and insects and that you’ve been swapping out some of your plants to help them. 

2. Validate how people feel if they mention specific plants. “I loved that as a child but now I know that it doesn’t support our insects.” “Now I know that using a native plant is more helpful.” “You know, when we know better, we can do better.” Use my food chart example to illustrate that we don’t have to get rid of all exotic plants.

3. Explain terms like exotic and invasive to convey that only some exotic plants are a problem. Include concepts about how the bad ones can disrupt the ecosystem and that wildlife/wind/water spread your seeds to other places; it's not always obvious to the person who has the plant.

4. Address concerns (Won't it be messy?). We know that we can use design principles to have aesthetically pleasing gardens with native plants. Encourage people to take it one step at a time and not be overwhelmed. 

Example of intentional design

5. Provide information like resources from the Georgia Native Plant Society and Homegrown National Park. Share social media groups (Facebook), people to follow (Instagram, TikTok), blogs, and podcasts that you have found helpful. 

6. Offer to help if you can: help dig up old shrubs for older people or offer to help research some ideas for replacements or where to buy them. Share some of your favorite native plant extras!

Feel free to use my graphics and my blog posts to illustrate concepts or provide recommendations. Spread the word!

September 2024 Moment in Nature

The diversity of native insects is amazing. I am always thrilled to find a less common one. This week found me leading a walking at Stone Mountain (where the number of Stone Mountain daisies was woefully down!). As we came down the trail we found a pair of walkingstick insects on a sign. What a way to brighten our day! It is definitely my #momentinnature for this month.

Walkingstick insects (there are two)

After some light research, it would appear these are the common walkingstick, Diapheromera femorata. These insects are herbivores. You can read more about them here.

Keep your eyes out for cool stuff! And if you're also missing the sight of Stone Mountain daisies (Helianthus porteri), here a photo from another year.

Ferns of Georgia

 

There are over 100 ferns native to Georgia and the Southeastern US. Some are big and bold while others are tiny, single-frond plants. Some spread on their own while others clump in a very tidy fashion. Like many native plants, some have evolved to live in special conditions (wet areas, rocky outcrops); quite a few of them are garden suitable and I’ve written about those Georgia ferns before. 

Christmas fern

Christmas fern (Polystichum acrostichoides) is one of our most well-known species for dryish shade; it is native to most of the state except for the coast; I profiled it in 2018 and included some landscape usage photos.

Recently I attended a talk about native ferns at our local chapter meeting. The speaker had a copy of a useful reference book that I had not seen before: Ferns of Alabama. Plants don’t follow state lines and there is a huge amount of overlap between the two states so this a good companion to our Georgia reference, Field Guide to the Ferns and Other Pteridophytes of Georgia. 

The books are not new; the Alabama one is 2012 and my copy of the Georgia one is 1986 but they apparently updated in 2003.

Both references have good introductory sections that I encourage folks to read because they give you a better understanding of how these plants grow (physical details of fern growth), how geology and geography affect what ferns grow where, as well as identification details for the different fern families.

The Georgia book has line drawings only but they are quite excellent, often including some important detail of the sori (reproductive structure). The Alabama book has line drawings as well as photographs. The Alabama book requires you to turn the page to see all the photos/text associated with one species, meaning that if the book is open then you might be looking at the description for one species and the photos of the previous one. I find that potentially confusing. The Georgia book shows everything on the same page spread.

Neither book has the latest Scientific names (and that is true for printed materials in a changing world), but the old name is easily cross-referenced using a resource like Flora of the Southeastern US (New York fern, as an example, is now Amauropelta noveboracensis, but you can easily use the old name Thelypteris noveboracensis to find the new name).

If you’re using these as a field guide, each book includes a natural range map by county, indicating where they grow in the wild. Each of them includes a few exotic ferns that have naturalized (although they don’t include one of the more recent naturalized ferns that I profiled in 2022).

I encourage you to get to know the ferns of your particular area and consider using them in your landscape for both beauty and functionality. While the ecosystem usage of these primitive plants is not as obvious as the host plants we use for insects, they serve as attractive and useful plantings, especially in shadier areas.

Prioritize Removal of Invasive Plants

 

Georgia roadsides are a mixed bag of vegetation but increasingly they are being swallowed up in invasive plants. In Georgia, we’ve all seen mounds of kudzu, stands of bamboo, thickets of privet, choking wisteria, and trees transformed into English ivy monsters. Joining them now are the large-leaved Princess trees, colonies of tree of heaven, thorny ornamental pears, chinaberry, mimosa, tallow tree. All of these are Category 1 invasive plants in Georgia. These plants are literally overtaking native plants, reducing the productiveness of our natural ecosystems, resulting in fewer pollinators, fewer birds, as well as other critters that depend on these.

Roadside English ivy, spreading towards neighbor

In this post I present 3 ideas that we could implement to help slow up these invasive plants.

I used to think that development would at least help clean some of this up. But that is not always the case; several newer neighborhoods near me kept all those road edges intact. New homeowners there appear to like the buffer that these thickets of privet and tree of heaven provide. The fruits and seeds from these plants continue to infest new areas, creating an even bigger problem.

Building approvals that should require developers to remove Category 1 invasive plants as a condition of the permitting process. With a smart phone in every hand, identifying invasive plants is not hard to do and should be part of the cost of development just like water management, roads, and utilities.

Kudzu, despite our knowing how bad it is, is actually worst now that before. Infested areas are spreading rapidly to new properties and seeds are dispersed even further. Why should property owners have to deal with the neglect of others? I am aware of one Georgia community that is drafting a ‘control of vegetation’ ordinance to require owners to manage invasive plants, especially when they move into adjacent properties due to lack of control: “An invasive plant owner shall not allow an invasive plant that is capable of spreading by runners, roots, vines, stems, bulbils, or rhizomes to spread from the invasive plant owner’s property to any public right-of-way or any adjoining property not owned by the invasive plant owner.”

Municipalities that manage their roadsides are capable of exerting the effort to actually remove invasive trees that grow into utility lines; unfortunately my personal observation is that they just prune them, ensuring that they will need another round next year while also allowing them to set seed and shade out native plants.

In summary: 1) require developers to remove invasive plants during construction; 2) create ordinances that require owners to contain any spreading invasive that they have; and 3) remove invasive plants in the right of way as part of regular roadside maintenance.

Great Southeast Pollinator Census – Year 6

The Great Southeast Pollinator Census is a fun citizen science activity that helps people get more acquainted with their local pollinators. It also helps them see which plants get good insect activity.

Pollinator census capture of skippers in love

I like to count in both the morning and afternoon to see how the pollinator activity changes. I enjoy watching how the different pollinators behave: for example, bumble bees move fast while carpenter bees lumber and prefer to crawl from flower to flower if they can.  

Every year that I do the census, it makes me think anew about how my pollinator garden can be more successful. In my 3-part pollinator series, I talked about several factors for supporting the most pollinators: using regional plants, providing for succession of blooms, having more than one of the same plant, and using different plants for different pollinators. If you haven't read it, dive into part one, part two, and part 3 at the hotlinks.

This is the sixth year of the census; it has expanded from Georgia-only to now include NC, SC, and FL. You are welcome to see my reports from the previous years, starting with 2023 (it has links to the older ones). Because the count is held during the same general timeframe each year, you'll see that I count on the same types of flowers each year (and I'm always amazed at well they support pollinators). It is clear from my counts that I have a really healthy bumble bee population!

August 2024 Moment in Nature

I am accustomed to seeing very little "real" nature in parking lots. If there are plants at all in the tiny islands between cars, they are usually non-native plants that have been pruned and sprayed into things that offer so little life to native critters that they might as well be plastic.

Partridge pea is a native annual

On a trip to the grocery store this week I was totally surprised and delighted to spy this small partridge pea (Chamaecrista fasciculata), a native annual plant that is very useful to native bumble bees and is also a host plant to Cloudless sulphur butterflies. It was a joyful #momentinnature in an otherwise mundane outing.

As I leaned over to take this photo, cars coming and going, I said a silent wish for some hungry bee to stumble upon it, its buzz pollination helping this single plant to make a few seeds to carry on in 2025. 

Reconnect with Local Nature

We don’t have to go far to reconnect with nature: no expensive trip to a national park or road trip to another part of the state; no corralling the kids with juice boxes and snacks to get in the car; and no pricey admission fee. Just get out and walk around your neighborhood.

Tortoise Beetle in my yard in 2014

I have found so many cool things in my yard and within walking distance and it gives me a quick uplift to refresh my sense of natural things. More and more data is coming out that time in nature is good for your health - both your physical and mental health. An article came out recently (and this is a gift link to it) that specifically talks about the impact on developing youngsters: “Time outdoors — even a walk around the neighborhood — helps children’s cognition, stress levels and general growth.”

“The average American today spends nearly 90 percent of their time indoors, according to the Environmental Protection Agency. Yet research indicates that children benefit greatly from time spent in nature; that not only does it improve their cognition, mood, self-esteem and social skills, but it can also make them physically healthier and less anxious.”

This is not a new concept; Richard Louv has written about it before in his book “Last Child in the Woods: Saving Our Children from Nature-Deficit Disorder.” I have reviewed his other book in the past, “Vitamin N: The Essential Guide to a Nature-Rich Life.” Between screen time and outsourcing the yard work to a lawn service, at-home outdoor time consists of going to the mailbox and filling the birdfeeder. We need to do more!

So apply a little sunscreen, add a spritz of bug spray and get out there to see what’s happening. Snap photos of unknown critters and then research them together to see what you found. Tools like iNaturalist and helpful online resources/identification groups can help you figure it out.

Clean Up and Get Ready to Count

I enjoy participating in the citizen science project known as The Great Southeast Pollinator Census. Originally started in Georgia in 2019, it now includes South Carolina, North Carolina, and Florida. Timed so that school kids can also participate, the census aims to increase awareness of our pollinators by asking people to spend at least 15 minutes counting them. By increasing awareness, we increase the chance that people will take steps to protect them. In addition to providing resources for the count itself (including a printable form), the census website includes resources about creating a pollinator garden and even recommends using native plants.

Early instar Jorō in front of same flowers

In preparation for the count, I now have a new step: remove Jorō spider webs from around my pollinator garden areas. I first wrote about these in 2020 to bring awareness to their spread. I wrote about them again in 2021 (link here) where I encouraged people to remove them to protect our pollinators. The folks at UGA originally suggested that residents didn’t have to do anything about them. In recognition of their impact on pollinators, however, they finally updated their guidance in 2023 to recommend that webs be removed in two areas: “The two places where no one should allow the webs to remain are around pollinator or flower gardens and bee hives.”

Later instar Jorō has larger web with gold threads

Start getting ready now by looking for webs (the UGA article has really good photos of the different growth instars to help you recognize them) and using long sticks and brooms to clear the webs and destroy the spiders so that our pollinators have the best chance of doing what they need to do.  

So, sharpen your pencils, read up on the guidelines, and get counting! The count period will be August 23 and 24, 2024. If you need a place to count, many local community gardens are offering guided counts and beautiful flowers on which to count. If you see something unusual, snap a quick photo and get help figuring it out after the count. You can read my earlier blogs about my participation in the counts all the way back to the beginning.

What Do July Rains Bring?

 

It has been dreadfully hot already this year and we’ve had some significant dry spells. It’s been hard on blooming plants and some of my established fern colonies were shedding fronds. I was out of town for about 9 days at the end of July and it sounds like we got a lot of rain (and indeed, one of my empty buckets had at least 8 inches of water in it!). This report by WSB confirms that some areas of Atlanta have gotten almost 13 inches of rain in one month. I’m sure some areas got more.

Woodland spiderlily

Before I went out of town, I had given up hope that my spiderlilies (Hymenocallis occidentalis var. occidentalis) would be blooming this year. This species doesn’t need to live in water like Shoals spiderlily (H. coronaria) but they do need good moisture. I was thrilled to see my plants blooming happily when I got home.

Ferns that had struggled with the heat have perked up. Mushrooms are sprouting and I found a large cauliflower one (Sparassis sp.) near the mailbox. I hadn’t seen one of these in years in my yard, but I figured the spores were still around.

Cauliflower mushroom

Here’s hoping the late summer blooms will benefit from the rain. It’s almost time for the Great Southeast Pollinator Census!
