Species Rating Tables

This species summary table provides a list of agronomic and native grasses and legumes, and rates their adaptive characteristics for important climate, soil and other characteristics. The table also provides suitability ratings for three common rangeland seeding objectives (forage enhancement, invasive plant suppression and erosion control).

Suitability & Adaptation Ratings
L = Low
M = Moderate
H = High

Species ratings for different characteristics are subjective and approximate. Special adaptive considerations have been added for the Peace River region (PR notes). Precipitation values attempt to reflect an adapted range rather than absolute limits—reported values, especially maximums, are highly variable. Ease of establishment ratings are also subjective. Actual results will vary depending on the seeding method, the seedbed, and moisture conditions. In general, improved establishment can be expected with drilled seeding methods, or broadcast methods that employ some form of post seeding disturbance (see application methods). Some species (e.g., Russian wildrye) can be difficult to establish even when direct seeding methods are used. Soil surface conditions that allow soil-to-seed contact and safe microsites for germination are critical in broadcast seeding applications where no post-seeding disturbance is planned. Smaller-seeded species like timothy, clovers, and fine fescues are better surface germinators, and
might be considered in those situations.
