5e. Conservation management recommendations |
|
|
Genetic differentiation / Genetic diversity / Inbreeding |
Conservation
strategy |
|
Low / High / Low
Populations have historically been connected maintaining high levels of
gene flow and are genetically healthy. Translocation between populations
is a viable option. No expected negative effects from local adaptation
or outbreeding depression unless there are strong environmental
gradients.
|
No management needed at this time. Only if management is to be
considered: maintain population sizes and gene flow.
|
|
Low / High / High
Populations have historically been connected maintaining high levels of
gene flow. Risk of population declines due to inbreeding depression. No
expected negative effects from local adaptation or outbreeding
depression unless there are strong environmental gradients.
|
Manage populations to reduce breeding between genetically related
individuals: facilitate pollen and seed immigration, translocations to
increase population sizes and introduce new genetic diversity.
|
|
Low / Low / Low
Populations have historically been connected. Mating patterns are
maintained but diversity has eroded due to low population size, founder,
or bottleneck effects. No expected negative effects from local
adaptation or outbreeding depression unless there are strong
environmental gradients.
|
Manage to increase genetic diversity: in-situ conservation action
(reduce disturbance), increase recruitment, facilitate pollen and seed
immigration, translocations.
|
|
Low / Low / High
Populations have historically been connected. Inbreeding is present and
exacerbated by low genetic diversity. Populations are not genetically
differentiated.
|
Manage to increase genetic diversity: in-situ (recovery from soil
seedbank), facilitate immigration, translocations.
|
|
High / High / Low
Populations historically isolated, little, or no current gene flow.
Healthy genetic diversity but populations genetically differentiated.
Populations are divergent and considered as conservation units: higher
risk of outbreeding depression.
|
Manage to maintain as many populations across the species range as
possible and to maintain large size. Translocations not recommended.
Manage habitat and ecological threats to maintain population size and
number.
|
|
High / High / High
Populations historically isolated, little, or no current gene flow, thus
genetically divergent. Populations retain high genetic diversity but are
inbred.
|
Manage populations to increase breeding between genetically unrelated
individuals. Translocations would be risky due to potential outbreeding
depression. Manage to increase breeding of unrelated individuals.
|
|
High / Low / Low
Populations historically isolated. Mating patterns maintained but gene
flow and genetic diversity are low.
|
Manage to increase genetic diversity. Consider composite provenancing
translocation if outbreeding risk is low or apply in-situ conservation
action.
|
|
High / Low / High
Populations historically isolated, little, or no current gene flow, thus
genetically divergent. Genetic diversity low and unlikely to be
resilient to environmental changes.
|
Intensive and costly management. Recover diversity in-situ and consider
translocations if outbreeding depression risks can be managed.
