Fig. 7From: Using classification assignment rules to assess land-use change impacts on forest biodiversity at local-to-national scalesRelationship between sample effort per catchment and the number of (a) alliances and (b) associations recorded and the size of each catchment with the number of (c) alliances and (d) associations. Outlier plots are not included in the number of alliances or associations. Relationships were fit as Generalised Additive Models using the R package mgcv (Wood 2017). The response was modelled using a Poisson distribution and cubic regression splines. Confidence intervals for the predicted values are indicated. The Mokihinui catchment is indicated by a black filled circleBack to article page
