jnross4's Identifications

Population of about 500 fruiting stems found in low spot in a mostly upland area that had been logged recently. A smaller population was found about 135 ft to the SW in another low spot. Only 14 fruiting stems were found there, but it appeared that some juveniles were present.

Besides being logged, furrows had been cut every ten feet, probably in preparation for it being replanted.

Soil sandy, standing water in the furrows. The two spots with standing water were the only places where I found the sedge.

Associated species were Rubus hispidus, cinnamon fern, and Lysimachia quadrifolia. On the higher areas, more upland plants were seen such as Carex pensylvanica and black oak.

This is the most concentrated population of C. cumulata that I have ever seen.

NEW area of 3 in flower at the now southern end of population where two trees had been girdled that previously caused heavy shade.
The western edge of the population has increased several meters to the west with a new location of 1 flowering individual located adjacent to a previously girdled cherry tree (which would have been heavy shade prior to two years ago).

12 total in flower and one non-flowering clump or 2024. (Only 1 flowering observed two years ago prior to brush clearing.)

2023 info for this population found here:

In the growing season of 2023, vegetation was still recovering from previous shade (not as dense) making the non-flowering clumps at that time easier to locate. Higher vegetation density exists now in 2024 making locating non-flowering clumps more difficult.

Known sub pop. 38 total (includes 12 in flower).

North group:
Main cluster with 10 (including 3 in flower).
2 additional non-flowering clumps towards SSW a meter plus.
1 flowering NNE 2.25m from center north (1.25 from edge) along with 3 non flowering within 0.75 m to west

1 non flowering east of main cluster ~1.25m

14 total in this grouping (4 in F)

Center group: 5 (including 2 in flower)
2 nf clumps additional towards west and southwest by 0.7m.
1 nf west of group 1.2m.

7 total in this center grouping (2 in F).

Single 1 between the south and middle grouping (previously covered by brush two years back) in bud

South group:

• 12 (including 5 in flower) in a 1.75m E/W by <1 m N/S area.
• 3 additional NF to north. 1.3m with m spread east to west.

• 1 flowering existing towards ENW 1.5m.
  16 total in this south grouping (6 in F).

Area was logged recently. It gently slopes to the south. Most were found along a skidder trail along the lower elevations.
Open cover.
Associated species include Carex intumescens, Rubus hispidus, red maple, white pine, C. adusta, C. brunnescens, Scirpus cyperinus, C. scoparia, Cinnamon fern, C debilis

Area was logged early last year. I looked here later that year and didn't find any. This year scattered clumps were found. Most were along a skidder track.
Because of recent rains, the whole area was very wet, with standing water in some places. One clump was in ponded depression.
Soil sandy, mostly open cover. A few large white pines were left standing.
Associated species included Carex adusta, which was the dominant herbaceous species. Also found were Carex debilis, Scirpus cyperinus, Dichanthelium sp, Acer rubrum, white pine, Carex lurida, and Juncus effusus.
There is an ATV trail that runs through the cutoff area but there was no evidence that ATVs were going off the trail.

Area was logged a few years ago. Two clumps were found on a level area on a south facing slope.
Soil sandy, dry to mesic moisture. Open cover.
Associated species included Rubus idaeus, bracken fern, Carex pen, Dichan sp, white pine.

Found along a logging road and adjacent logged area.
Open, sandy soil ranging from dry to wet.
Disturbed by logging.
Associated plants include Carex scoparia, C. pen, Danthonia spicata. One clump was in sphagnum moss.

153 stems found along logging road. 99 stems found in cut-off area near road.
Area is open. Soil sandy, wet.
Disturbed by logging.
Associated species include Carex debilis, Scirpus cyperinus, Juncus canadensis, Rhynchospora capitellata, Acer rubrum, Pinus strobus

Largest population I've seen. Extremely abundant in old field where Zizia is co-dominant, also abundant in adjacent shrub thicket transition to mature mixed hardwood bright woodland (bright enough for continuous, diverse sedge cover and abundant later forbs like forked aster). 1000 is an estimate of how many clumps passed my view, but the total population is probably 1 or 2 orders of magintude larger.
