Crowns of some of the cool -season grasses are <br />showing some greening up due to moisture from recent precipitation events. Slopes exhibiting very thin <br />vegetation establishment and resulting rilling need to be evaluated for ril l repair, surface roughening and repaired <br />area seeding prior to this growing season. NECC is advised to maximize seasonal precipitation patterns. <br /> <br /> <br />DOCUMENTS RECEIVED None <br />OTHER (SPECIFY) <br /> <br />
