3. Key word
Symbiosis- 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.
4. 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.
5. Introduction
Biodiversity 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.
6. Fungi
Fungi is kingdom that
includes mushrooms,
mold, yeast and
toadstools. Fungi may be
the cause of any member
of diseases in humans,
animals, and plant.
7. Lichens
The 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.
8. Bryophytes
Some 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.
9. Vascular Plants
Hundreds 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.
10. Invertebrates
Invertebrates are a vast and diverse group of species
that occupy nearly every conceivable niche in forest
ecosystems, including the interiors of other organism.
12. Fish
The 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.
13. Amphibians
There 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).
14. Reptiles
There are no species of
reptiles that seem to be
closely associated with
old growth forests per se
in the Pacific Northwest.
15. Birds
Thirty-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.
16. 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
17. Conclusion
Old growth features include diverse tree-related
structures that provide diverse wildlife habitat that
increases the biodiversity of the forest ecosystem.
