The assessor's comments

Woodlots along Sallow Creek and in the East Block, with riparian forest lining most of the creek. Draft layout clears about 38 acres of trees. Canada thistle, a state noxious weed, is scattered on field edges. No native prairie, rare natural communities or old-growth forest were found, though parts of East Block woodlots were not accessible.

Worst case

The same rule on the worst case gives no rating above the point.

Scenario

The East Block woodlots prove larger than mapped and the final layout clears more than 38 acres, but forest stays a small share of the site, so mitigation and seasonal windows remain routine.

Step still pending

2What the record shows

The five inputs

  • Present: yes

    Land cover includes woodlots along Sallow Creek and on reclaimed mine ground in the East Block (C-9d4b1ab8e4), riparian forest lining most of Sallow Creek (C-e10af45ca9), and a draft layout that clears about 38 acres of trees (C-c0e63f6881). Canada thistle, a state noxious weed, is scattered on field edges (C-08f3573546). The survey found no native prairie remnants, rare natural communities or old-growth forest (C-100c2c5e80); that absence covers those communities only, and parts of the East Block woodlots were not accessible (C-421d66e93e), so it is not complete for those areas.

  • Extent: peripheral

    Cropland is 818 acres (72%) and reclaimed grassland 80 acres (7%) of the Project Area (C-67ba142a5a, C-a6c169a2d9). Woodlots sit along Sallow Creek and on East Block reclaimed ground (C-9d4b1ab8e4), and the draft layout clears about 38 acres of trees (C-c0e63f6881), small against 780 buildable acres. This is a judgment: some East Block woodlots were not accessible (C-421d66e93e), so their extent is not fully verified, and corridor or fragmentation effects are not documented.

    Cites C-67ba142a5a, C-a6c169a2d9, C-9d4b1ab8e4, C-c0e63f6881, C-421d66e93e

  • Avoidable: partly

    The draft layout clears about 38 acres of trees (C-c0e63f6881). The consultant recommends avoiding the riparian forest and the W-3 wetland stand (C-b1fad0c404; W-3 vegetation is rated under AQ-01). Some clearing for arrays and access remains, so avoidance is partial.

    Cites C-c0e63f6881, C-b1fad0c404

  • Pathway: standard

    The record shows no state forest-conversion rule, mapped rare community or contested approval. Routine measures apply: tree cutting October 1 to March 31, clearing outside the nesting season, native pollinator seed mix, vegetation management plan, and mowing outside April 15 to July 31 (C-ffa524ccb3, C-4e22698f2d, C-557a6ccbbf, C-d756845b5e). The Parcel 9 conservation easement area along Sallow Creek is to remain in natural riparian cover (C-828699d893), a siting constraint rather than a bar on the site.

    Cites C-ffa524ccb3, C-4e22698f2d, C-557a6ccbbf, C-d756845b5e, C-828699d893

  • Impact likely: yes

    The draft layout clears about 38 acres of trees (C-c0e63f6881). Canada thistle, a state noxious weed, is documented on field edges, and solar grading would disturb soil there (C-08f3573546). Clearing alone makes the impact likely.

5Next steps and agencies

Next steps

  • Survey inaccessible East Block woodlots and measure forest by acre.
  • Refine layout to avoid riparian forest and the W-3 wetland stand and reduce clearing.
  • Prepare vegetation management and invasive species plan with native pollinator seed mix; clear trees October 1 to March 31.

6Basis and limits

This report is a desk review of the documents quoted above, as the engine read them for an information cut-off of 2023-08-01.

It is not a field survey and not a modelled study: this review made no site visit and ran no acoustic, hydraulic or other model. Where the record is silent, the report says what is missing; it does not fill the gap.

Every statement, figure and quote is the engine's record as written. The headings and connecting words are fixed text of this room, the same in every report.
