Lecture 11: Botanical Gardens Flashcards
1
Q
Plants compared to vertebrates
A
- hybridize easily
- not sensitive to inbreeding depression
- set seed - compact natural germplasm storage form
- propagated from small tissue samples
- easy to translocate
- plant conservation: utilitarian form
- used for medicine, cultural practices, and food
- different public perception
2
Q
Global plant diversity
A
greater diversity in south america and eastern asia
3
Q
endemic plant species across canada
A
- 93 total endemic plant species
- mainly in the northwest
- areas of high diversity are also areas of highest human impacts
4
Q
Red Mulberry
A
- IUCN: least concern
- Canada: Endangered
- shrinking due to habitat loss and hybridization of the white mulberry
5
Q
Hoary Mountain Mint
A
- Canada: endangered
- dumping of garden waste, invasive species (exotic woody plants), habitat loss
6
Q
Few-flowered club-rush
A
- Canada: endangered
- only canadian population around cootes paradise
- invasive plants
7

A
- Red mulberry
- Hoary Mountain Mint
- Few flowered club rush
8
Q
Plant conservation in action: in-situ (method of choice)
A
- protection of natural areas
- remediation of threats to populations
- ecological restoration
- population supplementation
- habitat connectivity
- genetic diversity
- population and dispersal ecology
9
Q
Plant conservation in action: ex-situ
A
- protection of living plants in cultivation
- seed gene bank
- tissue banks
10
Q
Botanical Gardens
A
-institutions holding documented collections of living plants for scientific research, conservation, display, and education.
11
Q
Conservation in zoos vs botanical gardens
A
- less emphasis on genetic diversity in botanical gardens
- recently has “studbook” approach for key species
12
Q
The Conservation Continuum
A
- Intrigue and excite
- Enrich the visitor experience
- Enrich and inform
- Caution and forewarn
- Equip to make a difference
13
Q
Botanic Gardens Conservation International (BGCI)
A
- established in 1987
- ~600 BG in 110 countries
- Developing Botanical garden policies and practices in plant conservation, environmental education, and sustainable development
14
Q
North American Botanic Garden Strategy for Plant conservation
A
- summary of BG’s contributions to plant conservation
- includes targets based on global botanic gardens targets developed in 2004
15
Q
ERA
A
- ecological restoration alliance of botanic gardens
- collaborative network of individuals, organizations, and communities to engage in ecological restoration
