JCWC’s Guide to Streamside Restoration
- Square footage or acreage and dimensions of the restoration area
- Land use – is the restoration area adjacent to agricultural fields, grazing cattle, houses, manicured lawn, etc?
- Current shade cover/level of native canopy present over the stream (this can be measured using a densitometer or an estimation of cover percentage)
- Aspect, and amount of sun reaching the restoration area
- Level of invasive cover (Armenian [Himalayan] blackberry, English ivy, and clematis are common). Take note of how much ground each invasive covers and how mature it is.
- Bank condition – note undercuts, landslides, or erosion
- General soil type and quality – sandy, clay, loamy – topsoil depth, level of contamination (litter, etc.) Is the soil compacted?
- Flood tendencies: Is the site inundated seasonally? How often does it flood?
- Other considerations – Beaver/nutria present? What culverts, rip-rap, or other man-made structures are present?
