Product Selection Matters
Erosion control product choice determines whether moisture reaches seeds and seedlings or is intercepted and lost.
Moisture-First Principle
On moisture-limited sites, any treatment that reduces soil moisture availability impedes the establishment you are trying to support.
Site-Specific Testing
Products must be tested against site-specific moisture regimes; no single product is appropriate across all BC biogeoclimatic zones.
Wexford: when surface cover is not drainage
This David Polster field record follows a moisture-sensitive highway slope from failed surface cover through living drainage, rooted cuttings, and later established vegetation.
Initial slope conditionA smooth wet slope gives water nowhere useful to go.
These are related field views from David Polster's Wexford source record, not a registered fixed-camera comparison. The later source frames are dated May 21, 2008 and March 23, 2010; the sequence describes visible conditions and treatment stages without assigning unverified dates to every frame.
