| Oak woodland bird assemblage |
| Pied flycatcher | UK BoCC Amber; IUCN Global & Eur LC; Local BAPs | - Woodlands require good and varied structure. Invasive non-native species, and high densities of deer, can be an issue.
- Long distance migrant – cause of decline not fully understood.
- Insectivorous – availability of prey and correct timing to avoid potential for mis match prey emergence and arrival time.
- Competition for nesting sites with resident species
- (Tree pipit only - can respond to clear-fell habitats but this is transitional mosaic species)

| Bird |
| Black grouse | S41; UK BoCC RED; IUCN Global LC; IUCN Eur LC; Local BAPs | - Requires a mosaic of habitats – moorland, bog, trees and scrub, varied vegetation structure.
- Benefits from a reduction in grazing (and a switch to cattle grazing).
- Chicks are fed invertebrates – restored hydrology on peatlands important.
- Woodlands and scrub provide important food sources for adults and cover in more severe winters.
|
| Cuckoo | S41; UK BoCC RED; IUCN Global & Eur LC; Local BAPs | - Availability of host species - particularly meadow pipit - in turn requiring invertebrate biomass and habitat mosaics of grassland and heather.
- Presence of woodland edge or scrub as part of a mosaic with grassland and heather.
- Abundance of prey, including hairy caterpillars and grasshoppers (both are highly vulnerable to mowing, high density livestock grazing and silage practices) [50].
|
| Dipper | UK BoCC Amber; IUCN Global & Eur LC | - Water quality supporting high numbers of invertebrates such as stonefly and caddis fly larvae
- Rocky in-channel and bank features
- Small falls for nesting sites that may be lost by channel modification/higher flows through canalization.
|
| Dunlin | UK BoCC RED; Local BAPs | - High quality restored blanket bog
|
| Hen harrier | BD Annex 1; S41; UK BoCC RED; IUCN Global LC; IUCN Eur NT; Local BAPs | - Absence of illegal persecution
- Presence of sufficient suitable nesting habitat (stands of long, older heather)
|
| Peregrine falcon | BD Annex 1; Local BAPs | |
| White-tailed eagle | BD Annex 1; UK BoCC AMBER; IUCN Global LC; IUCN Eur LC | - Robust ecosystems over a large area
- Absence of persecution
- Societal support for nature recovery.
|
| Ring ouzel | S41; UK BoCC Red; Local BAPs | - Mosaic of open and woody habitats including: diverse dwarf scrub sward and native woodland; shorter areas of grassy sward for feeding
- Native trees providing berries for autumn condition- especially juniper
- Protection of key sites from tree planting – well planned schemes and maintenance
- Long distant migrant – cause of decline not fully understood
|
| Mammal |
| Water vole | S41; IUCN GB Endangered; Local BAPs | - Lower livestock access to stream margins and channel – producing well-structured marginal and emergent vegetation (with ecosystem benefits including less suspended sediment, lowered cryptosporidium risk, increased roughness for water interception.)
- Good water vole habitat is likely to have slower flows, meanders, pools and offline features with benefits for flood and drought resilience.
|
| Beaver | IUCN Global & Eur LC; IUCN GB Endangered | - Rather than indicate the success of nature recovery, this species is likely to drive nature recovery by creating habitat for many other species. Its success may also indicate societal change in favour of nature recovery.
|
| Red squirrel | S41; IUCN Global LC; Local BAPs | - A more connected wooded landscape
- Decline in grey squirrel population
|
| Herptile |
| Adder | S41; IUCN Eur LC; Local BAPs | - Undisturbed, structurally heterogenous habitat mosaics (including a variety of aspects from east through south to west, for basking at different times of day/year
- Dry ground with cavities for hibernacula sites
- Nearby wetter ground for summer feeding, and safe passage between
- Improved public perception
|
| Common toad | S41; IUCN LC | - Require ponds and temporary water in the breeding season and nearby woodlands and scrubby habitat where they hibernate in deep leaf litter, log piles and burrows.
- Connectivity and safe passage between breeding ponds and wider habitat
|
| Fish |
| Atlantic salmon | HD Annex 2; HD Annex 5; S41; Local BAPs | - Clear fish passage to spawning grounds and for returning to the sea.
- Well oxygenated, lower temperature (0-12 °C) gravel rivers and streams for egg laying in redds. [58,59]
- River temperatures of 6-20 °C and good quality food resources and refugia areas from predators for parr. [58,59]
|
| Invertebrates |
| Bilberry bumble bee | On Natural England’s Species Recovery Programme (2012) because of modern evidence of serious decline | - Diverse and healthy heathland habitat mosaics
- Retention of species-rich haymeadows and banks
- Has a strong affinity with areas rich in bilberry and also requires species-rich grassland habitats (for legumes such as clovers and birds foot trefoils) in the same vicinity
|
| Moss carder bee | S41; IUCN Eur VU | - Permanent, flower-rich habitats and connectivity of these habitats
|
| Violet oil beetle | S41; IUCN GB LC | - Flower-rich habitats and the presence of mining bee species (particularly of the genera Andrena, Haliatus, Colletes, Osmia and Lasioglossum).
|
| Green hairstreak | Local BAPs | - Access to food plants: common rock-rose and common bird's-foot-trefoil on calcareous grassland; gorse, broom on heathland; bilberry on moorland.
- Heathland and woodland edge and scrubby grassland habitat.
|
| Large heath | S41; Local BAPs | - Access to food plant: Hare’s-tail cotton grass in mixed swards not dominated by cotton grass tussocks.
- Hydrologically intact peatland systems with low-level grazing reflecting plant productivity.
- Allow population movement by restricting dense woodland (particularly conifer plantation) in dispersal routes.
|
| Small pearl-bordered fritillary | S41; IUCN Eur LC; GB NT; Local BAPs | - Fen/marsh habitats (marsh violet food plant) with some shelter from wind by scrub/trees.
- Also, flower rich woodland glades (common dog-violet food plant).
|
| Arctic-Alpine assemblage |
| This is a large grouping, including over 170 species of plants which are of conservation concern, such as bird’s eye primrose, spring gentian and yellow marsh saxifrage. | - The requirements of each species are subtly different and there is ongoing research work into the distribution and ecological requirements of many of the species in Upper Teesdale.
- Of general importance to the assemblage will be maintaining the appropriate density and mix of grazing animals, the reduction in atmospheric nitrogen deposition, and the limiting of warming due to climate change and finding.
