assess the current status of the area are there any threats? wha t is he environmental history

restoration should be used to _____ conservation efforts not replace them

augment

why should the dam be removed?

it has no function it is filled with sediment and many species would benefit

what kind of genetic considerations should you have when restoring something? why does it matter?

it matters because genetic diversity matters for a healthy ecosystem are they local genotypes? do they belong where you are trying to plant them?

green streets curb cuts rain garden bioswale

what is the issue with restoring tidal flow?

historically speaking there is actually only this kind of flow for a small part of the year ; because its naturally a closed system and it would kill the habitat

how big will your restoration project be? what constraints do you have? physical, $

what type of species would you probably want to start with in restoration projects?

if its really screwed pioneer species

explain what she said about how hydrology changes flooding

if you mess with hydrology you mess with flooding patterns then animals who lay their eggs on the beach may be out of sync with the water so animals/eggs drown

what do we mean by "if you plant it, they will come"

if you put up plants the species will come as well

inbreeding

what does it mean to increase permeability of water into the ground?

increase infiltration of water through soil strata basically have more soil go through the soil where it will be filtered of toxins and other hydrocarbons

what is succession? why should you keep this in mind for

its the process by which the structures of a biological community evolve over time this kind of tells you what plants you can plant and which you can not ...as well as how your area will change with time

what is the current agreed upon plan for restoration of ballona creek?

restore the flow between the creek and the wetland by removing a concrete barrier to bring in tidal flow

what do we mean when we say restoration of an entire ecosystem?

returning a place to its historic state bring back biodiversity, processes, etc.

why do we want to increase permeability?

so it doesnt run into storm drains and into the oceans

why is it important for natural processes and inter species interactions to be included in restoration project?

soil is impacted by both and its literally the basis of the ecosystem which will determine what will live and what wont

what is a solution to ^^?

soil transplant

why are sediments so important for animals?

sometimes its needed for breeding of animals

what imporant thing did whooping crane loose the ability to do during the intensive breeding program? how are they fixing that

stopped migrating which is important in their life history they teach them the route by flying a small plane there and then monitor them through radio signals on an anklet; they all figure a way to get back

is it easier to preserve ecosystems or restore them? why?

to preserve we know how to preserve but restoring them is really complicated and we dont have that much info ..

what changes to landscapes/rivers do dams cause?

traps sediment which would usually flow with the water to be washed up to create coasts

what exactly is bioremediation

use fungus and bacteria to break down TCE, PCB, DDT and hydrocarbons

why both?

we want to remediate conditions when the option of conservation no longer exists but conserve whenever possible

why are some reasons why we would choose restoration?

when there isnt enough area of a certain habitat left when areas are highly degraded or fragmented

what is a situation in which you would want to use nurse plants?

when you have late successional species that you are planting and you want to help them thrive

what is the problem with buying plants from local nurseries?

you are unaware of the origin of the plant they may be from the wrong place in CA which may cause animals to not recognize them

why is an area with fennyl not going to be successful on its own?

you have to use round up to kill the plant.. it doesn't die any other way .. it cant take care of itself

what is the main message we learn from the arthropods

you need restoration to work at all trophic levels should look at all levels

should you always have to take care of the ecosystem? what do we expect from an ecosystem long term?

you shouldnt have to at some point the system should be able to move forward on its own

what are curb cuts

curbs that are constructed in such a way that excess water goes into this plant shed so it will infiltrate there

Conservation Permeability Retention

how much would it cost to remove the dam?

40 mill

water tx systems use what as a main source of remediation

bacteria

why do we have to start learning about restoration?

because there will be a lot more to conserve in the future; we are loosing habitat types

what are the IUCN guidelines on translocation/reintroduction

best to protect if the populations are naturally reproducing in the wild asses the risk to wild populations of doing this make sure threats are removed upon release comply with international standards reduce stress and suffering take disease and parasites into consideration

why was the malibu lagoon restoration controversial?

biodiversity was not listed as a goal

protection or restoration?

both

how do you ensure you are getting local genotypes?

by sourcing them yourself aka collecting seeds/individuals from a similar, local location

removal of a crossing in malibu creek state park which broke up habitat before

what is passive restoration?

removal of obstacles to natural regentation

removing some or all of the remaining indiiduals from a wild population to a facility where young can be produced and cared for with the objective of creating large numbers of individuals for re-release into the wild

what is replacement restoration?

replacing one degraded ecosystem with a different kind of ecosystem

what was the animal restoration example we talked about in class?

the blue butterfly project -- this was habitat enhancement -- protection of the sage scrub

what stops us from taking down dams like the one in malibu?

the sediment that has built up would probably destroy property , not even counting we dont know where we would put that sediment we have to buil a road to the dam to take sediment out

what is the major threat in the malibu creek that is affecting steelhead trout?

there is a dam that blocks the migration of the species

explain the whooping crane example... what happened, what is happening?

there used to be thousands but due to hunting there were only 15 by 1938 they then had to take all the animals in for an intensive breeding program ...

explain how mycelium can help with bioremediation

they absorb oil within 8 weeks production by producing enzymes that break down carbon bonds

what are the problems with cultivars?

they are rarely seen in nature so they are usually cultivated and cloned from a mother plant

explain the example about how anthropod diversity in coastal sage scrub....

they compared arthropod diversity at restoration sites and at natural sites they found that although on the large scale both sites looked good there was lower arthropod diversity, they have more invasives

what are some problems with putting plants from a nursery into a wild area?

they may have failure to thrive because they are accustomed to conditions in the nursery animals wont recognize them they wont develop the root system necesary to survive

what was the habitat restoration that took place at dockweiler beach? what did they do?

they tried to rebuild coastal habitat there was a lot of ice plant that initially was put in to stabilize the movement of sand but that actually is a natural ecosystem service the nonnative shallow rooted plant was keeping pollinators out

what are some ways we reconstruct environmental history?
