The key relationships from C6.

Findings	Relationship
% C6 analyzed in the study sample	97.87 %
Different contexts of times and places result in different popularity and success of PESPs	C6, C7→I, II, III: +
PESPs increasing with a great speed at all spatial scales [15,21,206] in both number of active PESPs and their ES values estimated and paid [[16], [17], [18]]	C6, II→C7: + & II, C6, C7→C1, C9: +
Negative link between age and effectiveness of PESPs [1,73,100] suggests careful consideration of all relative aspects of funding, payments and locality [100];	From C6, II→III: –to C6→C4, C7, C9: *
Common age of successful PESPs varies depending on different areas (cf. [1,100]);	C6, C7, II→III: +
Necessity of further studies in evaluating temporal and spatial dimensions for sustainability and success of PESPs [205].	C6, C7→C8: *
