Collected Evidence: Collected Evidence: Abandon plantations: allow marshes or swamps to recover without active interventionWe found no studies that evaluated the effects, on vegetation, of abandoning plantations with the expectation that marshes or swamps would recover spontaneously.   ‘We found no studies’ means that we have not yet found any studies that have directly evaluated this action during our systematic journal and report searches. Therefore we have been unable to assess whether or not the action is effective or has any harmful impacts. Please get in touch if you know of such a study for this action.Collected Evidencehttps%3A%2F%2Fconservationevidencejournal.com%2Factions%2F2956https%3A%2F%2Fconservationevidencejournal.com%2Factions%2F2956Thu, 25 Mar 2021 13:56:05 +0000Collected Evidence: Collected Evidence: Cut/remove/thin forest plantations: freshwater marshes One study evaluated the effects, on vegetation, of cutting/removing/thinning forest plantations to restore freshwater marshes. The study was in the USA. VEGETATION COMMUNITY Characteristic plant richness/diversity (1 study): One replicated, controlled study in the USA reported that the effect of thinning/clearing forest plantations on wetland-characteristic plant species richness depended on soil moisture. After three growing seasons, wetter thinned/cleared sites generally contained more wetland-characteristic plant species than drier thinned/cleared sites or sites that remained afforested.
