Heath Lake
Heath Lake is a biological Site of Special Scientific Interest (SSSI) in Berkshire. The SSSI is part of the Heathlake Local Nature Reserve, which is owned and managed by Wokingham District Council. Most of this lake is less than deep. It is the only acid lake in the county which retains its characteristic plants, such as alternate water-milfoil and six-stamened waterwort. The banks are peaty and marshy in some areas. There are also small areas of woodland, dry heath and acid grassland. There is access from Nine Mile Ride.

Site Of Special Scientific Interest
A Site of Special Scientific Interest (SSSI) in Great Britain or an Area of Special Scientific Interest (ASSI) in the Isle of Man and Northern Ireland is a conservation designation denoting a protected area in the United Kingdom and Isle of Man. SSSI/ASSIs are the basic building block of site-based nature conservation legislation and most other legal nature/geological conservation designations in the United Kingdom are based upon them, including national nature reserves, Ramsar sites, Special Protection Areas, and Special Areas of Conservation. The acronym "SSSI" is often pronounced "triple-S I". Selection and conservation Sites notified for their biological interest are known as Biological SSSIs (or ASSIs), and those notified for geological or physiographic interest are Geological SSSIs (or ASSIs). Sites may be divided into management units, with some areas including units that are noted for both biological and geological interest. Biological Biological SSSI/ASSIs may ...

Scots Pine
''Pinus sylvestris'', the Scots pine (UK), Scotch pine (US) or Baltic pine, is a species of tree in the pine family Pinaceae that is native to Eurasia. It can readily be identified by its combination of fairly short, blue-green leaves and orange-red bark. Description ''Pinus sylvestris'' is an evergreen coniferous tree growing up to in height and in trunk diameter when mature, exceptionally over tall and in trunk diameter on very productive sites. The tallest on record is a tree over 210 years old tree growing in Estonia which stands at . The lifespan is normally 150–300 years, with the oldest recorded specimens in Lapland, Northern Finland over 760 years. The bark is thick, flaky and orange-red when young to scaly and gray-brown in maturity, sometimes retaining the former on the upper portion.Trees for LifeSpecies profile: Scots pine/ref> The habit of the mature tree is distinctive due to its long, bare and straight trunk topped by a rounded or flat-topped mass of ...

Galium Palustre
''Galium palustre'', the common marsh bedstraw or simply marsh-bedstraw, is a herbaceous annual plant of the family Rubiaceae. This plant is widely distributed, native to virtually every country in Europe, plus Morocco, the Azores, Turkey, Turkmenistan, Western Siberia, Greenland, eastern Canada, St. Pierre & Miquelon, and parts of the United States (primarily the Michigan and the Northeast, but with isolated populations in Tennessee, Montana, Washington and Oregon). The species is classified as a noxious weed in New York, Pennsylvania, Massachusetts, Connecticut, Vermont and New Hampshire. It is considered naturalized in Kamchatka, Australia, New Zealand and Argentina. Ecology In Britain, ''Galium palustre'' is part of the British NVC Community M23 (Juncus effusus/acutiflorus – Galium palustre rush-pasture).

Ranunculus Flammula
''Ranunculus flammula'', the lesser spearwort, greater creeping spearwort or banewort, is a species of perennial herbaceous plants in the genus ''Ranunculus'' (buttercup), growing in damp places throughout the Boreal Kingdom. It flowers June/July. ''Ranunculus flammula'' is poisonous. It is very closely related to '' R. reptans'', which is distinguished by prostrate and more slender stems, narrower leaves and smaller flowers and is sometimes included within ''R. flammula'' sensu lato as a variety (''R. flammula'' var. ''reptans'' (L.) E. Meyer). In addition to other forms of pollination, this plant is adapted to rain-pollination.

Littorella Uniflora
''Littorella uniflora'' (vernacular name: (American) shoreweed) is a species of aquatic flowering plant native to the Azores, Morocco, most of Europe excluding the dry southeast, Iceland, and the Faroes. It prefers to live mostly submerged in nutrient-poor freshwater habitats. When submerged, it draws CO2 mostly through its roots and uses a mix of crassulacean acid metabolism Crassulacean acid metabolism, also known as CAM photosynthesis, is a carbon fixation pathway that evolved in some plants as an adaptation to arid conditions that allows a plant to photosynthesize during the day, but only exchange gases at night. ...

Potamogeton Pusillus
''Potamogeton pusillus'' is a species of aquatic plant known by the common names small pondweed, lesser pondweed or least pondweed. It occurs in standing and slow-flowing freshwater habitats throughout the Northern Hemisphere. Description Lesser pondweed is a superficially grasslike herb producing a very slender, branching, somewhat compressed stem, usually less than 70 cm but occasionally up to one metre in length. Nodal glands, if present, are generally poorly developed. The leaves are narrow and linear, translucent, mid or olive green, usually 20–50 mm long × 0.8-1.4 mm wide, but rarely up to 100 mm long and 1.9 mm wide. The midrib often lacks lacunae (transparent areas either side of the midrib) either side of it, and if present, lacunae are restricted to the lower half of the leaf. There are no floating leaves. The stipules are tubular when young, but tend to split with age. Turions are produced, often in large quantities. In early autumn the ...

Potamogeton Obtusifolius
''Potamogeton obtusifolius'', known as blunt-leaved pondweed, is an aquatic plant in the genus ''Potamogeton''. It grows mainly in mesotrophic to eutrophic lakes, ponds and ditches, rarely in brackish water. It occurs primarily in Central Europe, the British Isles, Fennoscandia and eastern North America. Description Blunt-leaved pondweed grows annually from turions and seed, producing branching plants with slender, flattened stems that have well-developed nodal glands (these appear as two raised bumps on the stem where the leaf attaches). The submerged leaves are long, rather grass-like, sessile, translucent leaves that are 48-85 (rarely up to 100) mm long and 1.5–3.55 mm wide and pale green, often with a very marked reddish or brownish tinge and a pink tinge along the midrib. There are 1-2 lateral veins either side of the midrib. As the name suggests, the leaf tips are rather blunt, though close inspection usually reveals a narrow point at the tip. The stipules are ...
