Habitat type • characteristic community of plants and animals closely linked with other environmental factors (light, warmth, humidity, light, soil type and structure)
• clearly separable from neighbouring habitat types • some examples: montane beech forest, riparian willow formation, common reed bed, highhigh-stem orchard, hay meadow, meadow, stream. stream.
