A suite of ecological and genetic factors are likely to contribute to reintroduction performance. Potential factors include the ecological similarity between seed source and introduction site, population size and genetic diversity of seed sources, and the habitat quality of the introduction site. We conducted common garden experiments with golden paintbrush (Castilleja levisecta), an endangered species from the Pacific Northwest, U.S.A., in order to test hypotheses about reintroduction… 

Microsites Matter: Improving the Success of Rare Species Reintroductions

Assessment of site suitability based on vegetation alone, and coarser, site-level assessments that do not characterize heterogeneity at the microsite scale, may not be strong predictors of restoration success over the longer term and in sites with variability in vegetation and soils.

Experimental reintroduction of three grassland forbs to assess climate-adjusted provenancing, grazing protection and weed control

The persistence of all populations suggests that admixture or climate-adjusted provenancing may be a realistic option to restore depleted populations of herbaceous plants in grassy eucalypt woodlands in a warming climate.

Effects of crossing distance on performance of the native wildflower Lobelia siphilitica: Implications for ecological restoration1

Mixed support for the recommendation that restoration projects use seed collected from geographically proximate populations is found, and factors other than geographic distance, particularly climatic distance, need to be considered when selecting seed sources for ecological restoration projects.

Habitat suitability and herbivores determine reintroduction success of an endangered legume

Genetic structure of Leucojum aestivum L. in the Po Valley (N-Italy) drives conservation management actions

The levels of population differentiation suggest that fragmentation in L. aestivum populations has occurred, but that an active gene flow between fragmented populations still exists, maintained by flooding events or pollinators, and should be considered when selecting source populations for translocation purposes.

Contribution of genetics for implementing population translocation of the threatened Arnica montana

This study investigated genetic variation and structure of the two last large and six small remaining populations of the self-incompatible, clonally-propagating Arnica montana in southern Belgium and bordering France to determine the genetic status of these remaining populations and whether the large populations can be used as seed source for translocations.

Genetic consequences of long-term isolation for the last French population of Eryngium viviparum (Apiaceae)

Using microsatellite markers, the genetic structure of the last French population was documented, and its genetic diversity was compared with ten Iberian populations, which cover the Atlantic region of Europe.

Predicting local adaptation in fragmented plant populations: implications for restoration genetics

This study indicates that for species in heterogeneous landscapes, collecting seed from large populations from similar environments to candidate sites is likely to provide the most appropriate seed sources for restoration.

Transplantation of the Subshrub Lotus scoparius: Testing the Home‐Site Advantage Hypothesis

The data support the home-site advantage hypothesis and the idea that mis-matching source populations of these genetically differentiated seed sources may result in lowered success of restored or constructed populations.

Nonlocal transplantation and outbreeding depression in the subshrub Lotus scoparius (Fabaceae).

The genetic background of transplants used to create or augment wild populations may affect the long-term success of restored populations. If seed sources are from differently adapted populations,

Competitive relationships of Andropogon gerardii (Big Bluestem) from remnant and restored native populations and select cultivated varieties

It is established that seed provenance and restoration activities influence the competitive ability of a dominant species which, in turn, may affect plant community structure and potential ecosystem function.

Direct and Indirect Effects of Host Plants: Implications for Reintroduction of an Endangered Hemiparasitic Plant (Castilleja levisecta)

This work examined how the performance of a rare Pacific Northwest hemiparasite, Castilleja levisecta, was affected by the availability of different host combinations in the greenhouse and in the field, and recommended planting with hosts that are not attractive to herbivores.

Conservation genetics of two co‐dominant grass species in an endangered grassland ecosystem

Research indicates that genetic diversity is much less of an issue in these perennial outcrossing autopolyploid grasses than genetic differences among local and non-local or cultivar seed sources, and suggests differences in plant performance as a function of the source population are more of a concern than genetic diversity.

Comparison of Isozymes and Quantitative Traits for Evaluating Patterns of Genetic Variation in Purple Needlegrass (Nassella pulchra)

The close association of quantitative trait variation with regional climatic variables indicates that an index based on readily obtainable climatic information might aid restorationists in making rapid decisions about appropriate spatial scales for translocating native grasses.

The recovery of an endangered plant. I. Creating a new population of Amsinckia grandiflora

Initial efforts to recover Amsinckia grandiflora Kleeb are reported on by re-establishing the species in appropriate habitat within its historic range, with consideration given to genetic and demographic characteristics of the founding population.

Rapid Genetic Decline in a Translocated Population of the Endangered Plant Grevillea scapigera

The results highlight the difficulty of maintaining genetic fidelity through a large translocation program and Strategies to reverse this genetic decline include equalizing founder numbers, adding new genotypes when discovered, optimizing genetic structure and plant density to promote multiple siring and reduce kinship.
