===''In situ'' sourcing===
''[[In-situ conservation|In situ]]'' sourcing for restorations involves moving individuals from an existing wild population to a new site where the species was formerly [[Local extinction|extirpated]]. Ideally, populations should be sourced ''in situ'' when possible due to the numerous risks associated with reintroducing organisms from captive populations to the wild.<ref name="IUCN 2017 Ex Situ">{{cite journal|last1=Maunder|first1=Mike|last2=Byers|first2=Onnie|title=The IUCN Technical Guidelines on the Management of Ex Situ Populations for Conservation: reflecting major changes in the application of ex situ conservation|journal=Oryx|date=January 2005|volume=39|issue=1|pages=95–98|doi=10.1017/S0030605305000177|doi-access=free}}</ref> To ensure that reintroduced populations have the best chance of surviving and reproducing, individuals should be sourced from populations that genetically and ecologically resemble the recipient population.<ref name=":1" /> Generally, sourcing from populations with similar environmental conditions to the reintroduction site will maximize the chance that reintroduced individuals are well adapted to the habitat of the reintroduction site otherwise there are possibilities that they will not take to their environment. .<ref name="Houde et al 2017">{{cite journal|last1=Houde|first1=Aimee|last2=Garner|first2=Shawn|last3=Neff|first3=Bryan|title=Restoring species through reintroductions: strategies for source population selection|journal=Restoration Ecology|date=2015|volume=23|issue=6|pages=746–753|doi=10.1111/rec.12280|bibcode=2015ResEc..23..746H |s2cid=83859097 }}</ref><ref name=":1">{{Cite journal|last1=Montalvo|first1=Arlee M.|last2=Ellstrand|first2=Norman C.|date=2000-08-15|title=Transplantation of the Subshrub Lotus scoparius: Testing the Home-Site Advantage Hypothesis|journal=Conservation Biology|language=en|volume=14|issue=4|pages=1034–1045|doi=10.1046/j.1523-1739.2000.99250.x|bibcode=2000ConBi..14.1034M |s2cid=84203019 |issn=0888-8892}}</ref>

One consideration for ''in situ'' sourcing is at which life stage the organisms should be collected, transported, and reintroduced. For instance, with plants, it is often ideal to transport them as seeds as they have the best chance of surviving translocation at this stage. However, some plants are difficult to establish as seed and may need to be translocated as juveniles or adults.<ref name="IUCN 2017 Guidelines"/>
