Conservation Evidence: Evidence Data

Collected Evidence: Collected Evidence: Make selective use of spring herbicidesA replicated, controlled, randomized study in the UK found that spring herbicides had some benefits for beneficial weeds and arthropods.

One replicated controlled and paired study from the Netherlands found higher plant diversity on ditch banks along unsprayed edges of winter wheat compared to those sprayed with pesticides. Three studies from the Netherlands and the UK (including two replicated site comparisons) found that ditch management had negative or no clear effects on some farmland bird species or plants.

One study found no population effects over three years. The second found slightly higher breeding densities of wading birds, but not higher overall numbers. A replicated and controlled study found higher hatching success of northern lapwing and black-tailed godwit on farms with payment schemes than control farms. A replicated site comparison from the Netherlands that looked at the effects of per-clutch payments in combination with postponed agricultural activities found more birds bred on 12.5 ha plots under the per-clutch payment and postponed agricultural activities scheme but found no differences at the field-scale.

All three also found that some species did not respond positively or responded negatively to management. A replicated, controlled and paired sites study from the UK found that bunded ditches were visited by more birds than non-bunded ditches.

The study was in a fen. Characteristic plants (1 study): One before-and-after study in a fen in the USA found that following restoration of water inflow across a road (along with general rewetting), cover of wet peatland sedges increased whilst cover of grasses preferring drier conditions decreased.

POPULATION RESPONSE (1 STUDY) Abundance (1 study): One paired sites study in Germany found higher overall bat activity (relative abundance) in a forest managed to encourage understorey growth than in a managed forest without understorey growth.

Two studies were in the USA and New Zealand and one was in each of Japan, Iran and Mexico. COMMUNITY RESPONSE (0 STUDIES) POPULATION RESPONSE (7 STUDIES) Reproductive success (7 studies): Five replicated studies in the USA, Japan, Iran and Mexico found that varying numbers of wild-caught snakes and lizards gave birth to live young or laid eggs that hatched successfully in captivity. One study also found that eggs laid in artificial nest chambers had higher hatching success than those laid outside of the chambers. One study in New Zealand found mixed effects of providing different basking conditions on the number of McCann’s skinks and common geckos that gave birth successfully. One controlled study in New Zealand found that McCann’s skinks in captivity that were treated for mites completed pregnancy more often and produced more viable offspring compared to skinks not treated.
