An environmental trust in the UK receives funding to restore a degraded lowland raised peat bog, aiming to conserve its unique biodiversity (such as sundews, Drosera spp.) and maintain its function as a carbon sink.

Which of the following management practices and ecological rationales is/are correct for conserving this ecosystem?

1. Blocking drainage ditches to raise the water table, which maintains anaerobic conditions and inhibits saprobionic decomposition of organic matter.
2. Regularly removing woody saplings (such as birch and willow) to prevent succession toward a woodland climax community.
3. Applying inorganic nitrogen fertilizer to promote the growth of dominant vascular plants and increase the net primary productivity (NPP) of the ecosystem.
