• birds, martins & bats (125)

• like thick trunks

• good insulation

• woodpeckers

• hack out 1 or two inch hole

• black woodpeckers

• work on multiple holes

• one for kids, one for sleeping

• take a month long break (126)

• fungi pitches in

• fungi keeps eating deeper

• woodpecker clears it out

• until hole too big for baby birds

• woodpecker moves out

• nuthatch (127)

• moves in

• closes up the too large entrance with mud

• wood conducts sound

• works as alarm for martins or squirrels

• if the bird has young can try to distract

• rarely works

• often have to try and raise a second brood

• bats

• some species need multiple homes to raise young (128)

• some species the females raise their young together

• spend only a few days in some quarters

• have to move before parasites move in

• owls

• need larger entrance

•trees try to heal wounds

• woodpeckers just hammer new wood away

•now rotting wood

• wood ants (129)

• fungi

• beetles

• animal excrement

• feeds bloodnecked click beetle

• hermit beetles

• can live in a tree for decades

• tree as community servant

• the more species diversity the less chance one will take over

Chapter 15 – In The Realm of Darkness

half of the biomass of forest is in the soil (85)

• most life can not be seen by naked eye

• more life forms in a handful of forest soil than people on the planet (86) is that true?

• teaspoonful contains miles of fungal filaments

when soil first created:

extraordinary to consider that soil is something that is formed over time – not something that just exists. i’m even more dismissive of it when I think of it as simply ‘dirt’. dirt feels dead – but soil feels alive and thriving

• geological processes in ice age

• sub zero temps

• glaciers ground down fragments

• created loosely packed substrate

• bacteria fungi and plants died to form humus

• trees moved in thousands of years later

• stabilized soil with root systems

• humus grows deeper

• early stages of bituminous coal

erosion

• forests left undisturbed

• lose only 1 to 14 tons of soil per square mile annually (87)

• soil becomes deeper and richer

• growing conditions constantly improve

animals

• beetle mites, springtails, pseudocentipedes

• first link in food chain

• terrestrial plankton

• countless species waiting to be discovered

beetles (88)

• oribatid mites

• live off leaves and bark fragments, and fungi

weevils

• ‘tiny elephants’

• most species-rich family of insects in the world (89)

• eat small holes in leaves

• plant eggs

• larvae eat their way out

• some species can no longer fly

• can only travel 30 ft per year at best

• only there if undisturbed forest

• forests cleared in middle ages won’t have them

• starve and die out in altered forests

will there ever be old growth forests again (90)

• bavarian forest (national park)

• microscopic organisms can cover long distances

• (by bird)

• if there are more undisturbed forests, they can make a comeback

Lüneberg Heath (91)

• planted oaks 100 years ago

• still gaps in microscopic species

• need preserves of ancient forests

• like Hümmel (92) with mixed use

• burial sites

• restore longleaf pines in southwest usa how so?

• ancient Caledonian Forests
