CONCLUSION

Key wordSymbiosis- the relation between two different species of organisms that

are interdependent.

Endemic- of or relating to a disease (or anything resembling a disease) constantly present to greater or lesser extent in a particular locality.

Mycelium- the vegetative part of a fungus consisting of a mass of branching threadlike hyphae.

Inconspicuous- not prominent or readily noticeable.

Antitrichia- wind in the atmosphere blowing above but in the opposite direction from the trade winds.

Curtipendula- the enclosed land around a house or other building.

Anadromous- migrating from the sea to freh water to spawn.

Objective This chapter aim the last several decades of ecological research is that the biological diversity of North American forests is far greater than previously thought.

IntroductionBiodiversity of forest and its influence on sustainability must be perceived as much more than just trees, fish, and wildlife and the presence and fate of individual species.

FungiFungi is kingdom that

includes mushrooms, mold, yeast and toadstools. Fungi may be the cause of any member of diseases in humans, animals, and plant.

LichensThe FEMAT team identified 157 lichen species closely associated with late-successional forests. Lichens contribute to nutrient cycling and biomass production and are critical in food chains of mammals and invertebrates.

BryophytesSome 106 species of bryophytes

(hornworts, liverworts, and mosses) found in the Pacific Northwest are closely associated with late-successional forests.

Most species of bryophytes do not become established in stands until 100 years, and they are best developed in stands 400 years and older.

Vascular PlantsHundreds of species of vascular

plants occur in late-successional forests of the Pacific Northwest. Some 127 of these species are closely associated with such forests.

Vascular plants also provide necessary habitats and feeling substrates for many vertebrate species.

InvertebratesInvertebrates are a vast and diverse group of species

that occupy nearly every conceivable niche in forest ecosystems, including the interiors of other organism.

ArthropodsArthropod are another

major group of invertebrates in northwest forests.

FishThe FEMAT team

identified 314 stock of at-risk salmonid fishes in old-growth forest landscapes within the range of the northern spotted owl in the Pacific Northwest.

AmphibiansThere are 62 species of

amphibians found in the Northwest. Old forests of the Northwest provide habitat for some relictual species (Welsh 1990) and the relatively high species diversity (Walls etal. 1992).

ReptilesThere are no species of

reptiles that seem to be closely associated with old growth forests per se in the Pacific Northwest.

BirdsThirty-eight species of

birds are closely associated with late successional forests, but none is endemic to the northwest.

Many bird species disperse seeds of conifers and flowering plants.

Mammals.  Mammals classes are groups of animals that scientists consider to be alike in some important ways.  Mammals  are the animal class that people belong to.

There are  only about 4,000 kinds of mammals

Conclusion

Old growth features include diverse tree-related structures that provide diverse wildlife habitat that increases the biodiversity of the forest ecosystem.
