Explore the habitat profile of Sidmouth's River Sid valley. Learn how history, "untidy" scrub, and invasive species like Winter Heliotrope shape this wildlife corridor.
The biodiversity of The Byes is a direct reflection of its history and its location. While it serves as a modern recreational space, the plants growing there today tell a story of past farming, garden escapes, and a commitment to "untidy" conservation.
The highest population index in the park is for cultivated and disturbed land. This is influenced by:
Farming History: Past agricultural use of the valley floor.
Garden "Escapes": Proximity to housing on the western flank has introduced non-native species.
Invasive Species: Learners should look out for Three-cornered Leek and Winter Heliotrope, which are problematic invaders in this network.
One of the most significant ecological findings is the abundance of broadleaved woodland, scrub, and hedgerow scrub.
Why Scrub Matters: While it can look "untidy," these scrubby hedgerows are vital for birds, mammals, and insects.
Diverse Trees: The "parkland and scattered trees" profile benefits bird species by creating an open woodland environment.
The valley floor’s damp conditions support a wide variety of flora:
Grasslands: Most species thrive in damp and neutral soil, though there are surprising pockets of acid "heath" and calcareous plants.
Freshwater Margins: The River Sid creates "standing water" environments in damp woodlands and ponds, supporting specialized aquatic vegetation.
This data shows the percentage of expected species currently present in the network.
Habitat Type Species Presence % Ecological Role
Parkland / Scattered Trees 80.0% High-value bird habitat
Hedgerow Scrub 77.8% Critical for mammals and insects
Neutral Grassland 75.0% Core meadow biodiversity
Broadleaved Woodland 68.4% Found in Upper Byes and riverside

Before you go:
Objective: Identify the influence of human proximity on natural habitats.
Field Observation: Walk the western border of The Byes (near the housing) and compare it to the more isolated "Upper Byes".
Identification: Can you find Three-cornered Leek or Winter Heliotrope? These are markers of "disturbed land".
The Scrub Check: Find a section of "untidy" scrub. Instead of seeing it as messy, list three things it provides for wildlife (e.g., shelter, nesting sites, berries).
