Collected Evidence: Collected Evidence: Practise wildlife gardening A site comparison study in one city in the UK found more species of bumblebee in domestic city gardens with lower intensity of management, a measure reflecting the tidiness of the garden and the use of garden pesticides. Solitary bees were not affected by this measure.  Collected Evidencehttps%3A%2F%2Fwww.conservationevidence.com%2Factions%2F2https%3A%2F%2Fwww.conservationevidence.com%2Factions%2F2Tue, 18 May 2010 07:40:30 +0100Collected Evidence: Collected Evidence: Practice integrated farm management We found no intervention-based evidence on the effects of practicing integrated farm management on bird populations.

One study was in Mexico and one was in the USA. COMMUNITY RESPONSE (0 STUDIES) POPULATION RESPONSE (2 STUDIES) Survival (2 studies): A study in Mexico found that a series of non-traditional techniques, combined with natural mating, produced five aoudad embryos that could be cryogenically preserved. A study in USA, found that artificial insemination using preserved genetic material increased genetic diversity and lowered inbreeding in a captive black‐footed ferret population.

Two were in the UK and one was in each of France and the USA. COMMUNITY RESPONSE (1 STUDY) Richness/diversity (1 study): One replicated, paired, controlled study in the USA found that areas with reduced frequency weeding had a similar species richness of adult butterflies compared to areas with conventional weeding. POPULATION RESPONSE (3 STUDIES) Abundance (3 studies): Two replicated studies (including one paired, controlled study) in the UK and the USA found that increasing the number and age of potted nettle plants in gardens and weeding less frequently did not increase abundance of butterflies, all caterpillars and caterpillars and eggs of four target species. One replicated, site comparison study in France found that gardens where insecticides and herbicides were not used and where there were natural features had a higher abundance of butterflies, but gardens where fungicides and snail pellets were not used had a lower abundance of butterflies. BEHAVIOUR (2 STUDIES) Use (2 studies): One replicated study in the UK reported that caterpillars only occasionally used potted nettle plants in gardens. One site comparison study in the UK found that planted buddleia and marjoram were visited by adult butterflies and moths more frequently than other plant species.
