A ruderal community beside the retaining wall

This lists, or begins to, the plant community of a ruderal habitat near our house that began about eight years ago. A backhoe tore up all the shallow weedy turf on a slope to the west of a 12-foot-high stone retaining wall to allow construction of concrete buttresses for the wall. From the wall to the Sawyer Kill is about 30 feet. The southern end is ¾ sun, the northern shaded. When the buttresses were finished, we spread imported loamy topsoil in a thin layer over most of the clayey slope and seeded the area (aprox 3000 square feet) with “No Mow” grass mix from Prairie Nursery. It took pretty well in the first two years, then began to be hidden under taller flora. We paid little attention to the succession since until this year, when I got belatedly interested in native plants.

A photo of the habitat from the south end is on

On August 29 I spent about half an hour noting the plants seen in this almost-all-volunteer community. All of them are in my I Nat album, though not all the observations are research grade. To my dismay, it seems that unless we intervene, the highly invasive mugwort soon will dominate at least the sunnier, southern, half of the arena. I was pleased to see, though, how many native plants are established without any help from us except for the kinds marked with an asterisk – one sapling each of two tree species, some transplanted Chasmanthium latifolium, and a couple of small clumps of two kinds of native fern.

I am indebted to the more than 400 i Nat community members who have guided me with identifications and suggestions since I joined in Dec 2021. Thank you all, and thanks to the organizers who built and run this extraordinary platform.

The streambank habitat

Below is a list of ninety-one kinds of plants I found along the 300 yards or so on both sides of the Sawyer Kill between the two bridges between Sept 5 and Sept 15. Three more have been added on October 1. The list is grouped by natives vs not, with Smoothcap moss (genus Atrichum) unclassified. Seventeen of the sixty natives had been planted by me from a nursery, most in 2023. Two species, denoted as t23, had been transplanted in 2023 from elsewhere on the farm. Forty-one of the natives, then, had been there without my interference/intervention.
As other plants are found I will add them, but note after the name of each when it was added.
The inventory here follows the same method as the other journal entry posted earlier about the ruderal habitat, but the habitat described here developed in a different way. When we moved to this farm thirty years ago the long-ungrazed cattle pasture on the left bank of the Sawyer Kill came almost to the lip of the steep bank. We decided to set electric fencing fifteen feet from the lip and not mow outside it, to let whatever volunteered grow into into a "streambank buffer" that would slow bank erosion, give cover to wildlife and keep sheep manure runoff out of the (un-pristine) stream.
Through my carelessness, the big trees (native and non-native) along the stream gradually found themselves standing in a dense tangle of invasive non-native plants. Chief contributors/offenders are Japanese barberry, Privet (species uncertain), Japanese honeysuckle, Multiflora rose, Winged euonymus, Oriental bittersweet and Autumn olive (which I confess to have transplanted a couple of decades ago). Sad to say, I did not realize the harm of this situation until hearing a webinar in spring 2023 about native plants and then reading Douglas Tallamy. Since then I've set about to take out non-natives and replace them with natives. In the process a number of native species already resident but often overwhelmed came to light. Some native ground covers and ramblers (Riparian grape, Virginia Creeper and Poison Ivy) were holding their own amidst Japanese honeysuckle, Bittersweet and Ground ivy.
The list is a snapshot of what we'll be working with and against to get natives on a stronger footing over the next few years.
I am most grateful to i Nat and the i Nat community of teachers and identifiers.
This journal page is dedicated to Don Wilkin, Ph.D., a mentor in ecology.

The downed oak habitat

In February 2022 an ice storm uprooted a huge oak west of the barns. It fell into a stand of younger trees growing in what eighty years before had been a cattle pasture. The photo below shows it in September 2023. The second photo of bark, moss, polypore and geranium is a microcosm of the whole little system. The third photo shows off the fungus most prevalent and most conspicuous in this little system as of September 2023. This is Sterum complicatum, along with a companion also heavily represented, Trichaptum biforme. Trametes betulina may be third-easiest to spot; it seems to be everywhere.
That autumn, while cleaning up some of the debris, I saw many fungi on the trunk and branches that caught my beginner's eye. I made close to seventy observations on i Nat in October-November and added three in September 2023. I got wonderful help from members of the i Nat community, notably Sarah Duhon, Misha Zitser and John Plischke and from NY Myco Society virtual ID sessions.
Among the seventy observations on this tiny ecosystem, twenty species of fungus and one of lichen have at least one Research Grade observation. A few species have several. Another seven observations of fungi are posted at the Genus level. These include some crust fungi, which that I've noticed are very hard to identify below Genus level from macro photos alone. One lichen is posted at species level that is not confirmed.
The twenty-nine observations of fungi (mostly) or lichen that are at Genus level or lower are listed below. A fungus with more than one RG observation is listed only once.
This was a good learning lab for me as a novice identifier privileged to interact with others who know much more. It's also the start of a chance to follow future outgrowths.
