Observation Narrative
Plot is located in a 5-ha stand of metabasalt woodland of exceptional quality. It captures the more open extreme that occurs on and around small outcrops, with graminoids (particularly Elymus hystrix var. hystrix) co-dominant in the herb layer. The cover of Phacelia dubia var. dubia was estimated from the abundant dried remains of this spring-flowering species.
