Other Site Characteristics

Lake Ågelsjön with its surrounding forests. The clear and very deep lake Ågelsjön is a good example of an oligotrophic lake, with an unusual long renewal time. In the lake is the glacialrelictspecies of crustacean's Mysis relicta and Monoporeia affinis found. The surrounding forest is large area of "western taiga"-habitat, with a very rich flora, mostly cryptogams as lichens and mosses but also fungi. The most interesting species are Cybebe gracilienta, Dicranodondium denudatum, Inonotus tomentosus and Phlebia centrifuga. In the forest are also parts with calcareous influenced ground with a rich flora, for example Polygonatum multiflorum, Cardamine bulbifera, Listera ovata and Sanicula europaéa. In the small areas that have been managed as pastureland for a long time ago, is the herb Campanula cervicaria and Agrimonia procera. The findings of insect fauna have so far relieved some very rare species, such as Osmoderma eremita. Of the breeding birds in the area should Columba oenas, Dryocopus martimus and Croccotraustes croccotraustes be mentioned. Lake Ågelsjön is a frequently used recreation area and is also of national interest of leisure and nature. Detailed description The Lake Lake Ågelsjön is a large oligotrophic lake, surrounded by forests of Western taiga-habitat. The north side of the lake has several steep mountains only broken by some small ravines or cracked valleys. Along the south side goes a more slight precipitate, which have given a more slender steep towards the lake. By the northwest part of the lake, at Övre and Nedre Ågelsjön, have the land former been used for grazing and surrounding forest have also been used by grazing cattle. The rest of the surrounding area to the lake, shows a very small affection by man (not included the area at Hultsbruk). The lake is very deep; the deepest point is 35 m from the water surface. There are three islands and some small islets in the lake. The watervegetation is over all poor with species as Carex rostrata, Equisetum fluviatile, Lysimachia thyrsiflora, Lobelia dortmanna, Juncus bulbosus and Myriophyllum alterniflorum. In shallow bays, mostly in the western parts, is species like Phragmites australis, Typha latifolia, Schoenoplectus lacustris, Carex vesicaria, Nymphaea alba and Potamogeton natans present. Gammarus sp. Oligothaeta sp. and species of Ephemeroptera dominate the benzoic fauna. Several species sensitive to acid water, lives in the lake. For example Caenis horaria and C. Luctuosa have been found. Gavia artica and Actitis hypolecos represent the bird fauna in the lake. In the lake is some species left from the days when Lake Ågelsjön and the Baltic sea was one big sea, these are the glacial relicts Mysis relicta and Monoporeia affinis. Pike, together with other usual freshwater species, is found in the lake. Until 1994 was a good population of the rare crustacean Astacus astacus prospering in the lake, but the virus decease has vanished this population. Several lakes and brooks upstream Lake Ågelsjön is managed with limestone or limepowder to rise the pH-level in the water. Today is the buffering-capacity good in Lake Ågelsjön. The forest The whole area is characterised by the tree-covered precipitate that surrounds the lake. Far up in the northwest is the forest not so dense and dominated with oak and Tilia cordata. In this area is some rocky meadows with a very rich flora, for example Geranium sanguineum, Origanum vulgare, Antennaria dioica, Polygala vulgaris, Luzula multiflora, Arabis hirsuta and Carex pilulifera. The open forest have several herbs that reveals the landuse history as grazed wood, there is spread findings of Platanthera bifolia, Trollius europaeus, Circum helenoides, Filipendula vulgaris, Linum cartharticum an the rare herbs Campanula cervicaria and Agrimonia procera. The tree-layer in the area is also interesting with several demanding species of lichens on broad-leaved trees. On Tilia cordata growes Shismatomma decolor

4.2 Quality and importance

Ågelsjön is important as a representative western taiga forest in a surrounding area with very intensive forestry management. The lake Ågelsjön is a good example of an oligotrophic lake. There are ancient remains in the area.
