The un-greyed region on the map is the 'genetically local area' or local neighbourhood, based on genetic data.

If the objective of your project is to restore this species from local provenance only, where possible, we encourage collection of material from multiple locations within the local provenance area to increase genetic variation, overall fitness and long-term viability of your restoration project.

In general, when sampling plant material for restoration, sampling from a greater number of individuals and from individuals further apart within the genetic neighbourhood will lead to greater genetic diversity. The graph below (based on a modelled simulation) shows that we can expect the genetic diversity captured to increase as more plants are collected, especially if the plants are far enough apart (thus decreasing the likelihood of them being closely related). The blue curve shows an outcome for a "mixed" strategy, where half the plants are collected near the restoration site, and the other half were collected from a site at the boundary of the local neighbourhood. Such a strategy produces greater diversity than collecting the same number of plants from the same location (red curve).

The blue curve shows an outcome for a sampling strategy that is not restricted to a single location. In this case, as an example, half the plants were collected from a location near the restoration site, and the other half were collected from a location close to the boundary of the local genetic provenance. Such a strategy produces much greater diversity (blue curve) than collecting the same number of plants from the same location (red curve). So even when restricting your sampling to the ‘local provenance’, it is generally best to sample from multiple individuals sourced from multiple locations. Although the extent of local provenance varies between locations and species, opportunities to maximise diversity are generally present.

For your selected species and location there are additional restoration strategies to choose from other than the basic ‘local provenance’ scenario described above. The section below suggests how to follow additional scenarios using our current understanding of how genetic diversity varies across the landscape for this species.

The areas that match the climate at your chosen site are shown shaded in purple. It is possible that this species has made subtle adaptations to the local environment. We cannot determine the degree of local adaptation with currently available genetic samples; it typically requires extensive experimental study. To make allowance for possible local adaptation, you may decide to collect material from similar environments to that present at your selected location. This information enables you to plan one or more replicable ‘composite provenancing’ strategy/ies that can be fitted within a comparative experimental model, or can be planned as a ‘one-off’ and monitored through time. Three possible scenarios include:

1. Local provenance, local climate: if you aim to plant genetically local material that fits climate (currently) similar to your selected site, collect from multiple locations in the following areas:
   • The areas that fall within the overlap between the local genetic provenance (non-greyed area on the map), and the climate matched regions (highlighted in purple).
2. Local composite: if you aim to plant genetically local material, but include the range of climatic conditions present within your local genetic provenance, collect from multiple locations in the two areas described below:
   • The local genetic provenance sites (non-greyed area on the map) that fall within climatic conditions that are matched to your selected site (purple highlight).
   • The local genetic provenance sites (non-greyed area on the map) that fall outside matched climatic conditions.
3. Mixed composite: if you aim to collect plant material from climatic conditions similar to those at your site but from multiple genetic provenances, collect from multiple locations in the two areas described below:
   • The overlap between the local genetic provenance (non-greyed area on the map), and regions climatically matched to your selected site (highlighted in purple).
   • Areas climatically matching the conditions on your selected site but found outside the local genetic provenance (highlighted in purple within the greyed area).
