Not the best images - I took these off my voucher specimen later in the day when the host tissue had dried up and curled inward.
Locally common on marram grass (Ammophila arenaria) in sand dunes.
Common in garden bed, but seemingly not planted.
Rhizomatous perennial, some rhizomes with scaly tubers. Common in sand areas.
Bushy grass seeds at ends that appear loose and ready to spread. Stems are thing and turn brown.
Arnica?
A native moth feeding on nectar and perhaps pollinating an invasive plant, Ragwort (Jacobaea vulgaris).
Earlier in the year, I noticed holes in the leaves of S. dulcamara but I never saw what created them. The holes reminded me of ones made by Black-margined Loosestrife Beetles (Galerucella calmariensis) on Purple Loosestrife (Lythrum salicaria). Today I found a G. calmariensis on a hole ridden S. dulcamara leaf.
I see rabbits eating blackberry canes in the winter. In the spring, I have seen them eating new blackberry leaves before the spines on the leaves develop. The new growth is a good source of dietary nitrogen.

A native insect found hunting on invasive Tansy.
While it does not seem to make a major impact on the Tansy population in the park, this indigenous caterpillar blends in well with the plant as it feeds on its flowers.
Grains not the same size
Invasive sp, large colony in one meadow; control efforts needed before it spreads
The butterfly is in the middle, under a leaf, mostly obscured by the shade, where it is laying an egg!
Two years ago, after someone dug up the nettle patch in my growing butterfly meadow, where I often see Satyr Commas, I planted a nettle root, which grew into this nettle patch. I was very happy to see this one landing on the nettles, laying an egg on the underside of a leaf, taking a flight, land on the nettles again, and lay another egg on the underside of another leaf. It repeated this about seven times. I look forward to seeing the caterpillars!
The caterpillars will stay on the underside of the leaf, and make a tent by pulling the sides of the leaf down, and together with silk, leaving the front half of the leaf open, and will feed from the tip of the leaf to the petiole, leaving a petiole with no blade when they are done, then go to a new leaf, and do the same. In the 4th photo someone has pulled open the tent, the caterpillar was hiding under, to expose the caterpillar.
My journal post of how the egg laying on these Stinging Nettles was my first observed success in 27 years of working to get butterflies to lay eggs on plants growing where I started them growing!
A native annual with a predilection for disturbance-prone settings, little barley was especially abundant during a summer following a dry fall and winter and when most other plant species were not flowering.

The inflorescence of six row barley includes three rows of seed bearing florets on each side (corresponding the three spikelets per node and spikelets alternating along opposite sides of the rachis). Six row barley has the thicker and darker inflorescences and is growing along the margins of a field of two row barley. This barley represents populations that have escaped from the adjacent crop fields of the Museum of the Rockies and established along South 7th Street, Bozeman, Montana.

Hare barley is not really known from Montana but here it is growing in farm west of Broadview, Montana, in Yellowstone County.
Hare barley is an introduced annual bunchgrass often growing roadside, trailside, and in similarly disturbed settings. A distinctive Hordeum species because of the three spikelets per node, the lateral two of which produce a well-developed staminate floret. The glumes of the central fertile spikelet are distinctively lined with ciliate hairs. In addition, the clasping auricles are well developed in this species compared to other annual non-crop Hordeum species.
The spike is fairly large, often about 2 cm in diameter. At each inflorescence node, the lateral spikelets are as large as the central one, analogous to the condition in six-row barley. This site lies in Eureka, Humboldt County, California.
This might be Cow Parsnip, at least I hope it is
We see these about once a year, usually on our screen door. They remain for a couple of days, then are gone. This one showed up on 4/9 and is still in its spot on the north side of the house today, 4/11. Might it be any other species of plume moth?
Gravelly area, seen throughout the island.
Sensu lato (although ssp. leersii reported from Pelee Island). Weedy shallow-soiled meadow over limestone.
Flora of the Pacific Northwest differentiates J. maritima and the hybrid with J. vulgaris based on the achenes being puberulent for the hybrid and glabrous for J. maritima. Also the hybrid is intermediate in habit and pubescence. There are a couple plants on the site with a perennial habit and many stems.

I saw this far from any cultivated plants, but I know there are some in yards on Burton Peninsula. I haven't noticed any the Burton Acres Park before, but I was focusing on invasives today more than I usually do. I assume my proposed ID is correct, but I also hope it isn't!
On my walk in Burton Acres Park today, I saw 12 non-native, escaped plant species I wish I hadn't seen and three (at the bottom of the list) I was happy to see.
