Providing evidence to improve practice

The journal, Conservation Evidence

Our online journal publishes research, monitoring results and case studies on the effects of conservation interventions. All papers include some monitoring of the effects of the intervention and are written by, or in partnership with, those who did the conservation work. It includes interventions such as habitat creation, habitat restoration, translocations, reintroductions, invasive species control, and education or integrated conservation development programmes, from anywhere around the world.

A volume is created each year with peer-reviewed papers published throughout the year. We now accept Short Communications as well as standard papers.

Special issues contain new papers on a specific topic.

Virtual collections collate papers published in the journal on specific topics such as management of particular groups of species.

Highly invasive, non-native Japanese knotweed Fallopia japonica, was successfully controlled, although not completely eradicated, by cut and inject herbicide application in a coastal valley in south-west England. In areas cleared of knotweed infestation, native flora including bluebells Hyacinthoides non-scripta, successfully re-established.

Trials at sites infested with the highly invasive Japanese knotweed Fallopia japonica, in southwest England, demonstrated that a cut and inject method of herbicide application is an effective way of controlling the plant. Although not matching the kill of the more commonly used method of foliar spraying, it did allow very selective application. Thus the cut and inject method can effectively avoid damage to non-target species and allows herbicidal treatment near watercourses where foliar spraying may not be permitted.

Dredging the silt from two old ponds in southern England (one in which the nationally endangered starfruit Damasonium alisma had recently been rediscovered) resulted in dramatic initial results, with many starfruit plants appearing. A subsequent rapid fall off in numbers suggests that seeds appear to germinate best on exposed sediment on drying margins and continuous low-level disturbance management is probably desirable.

Dune restoration through herbicide control of non-native, invasive marram grass Ammophila arenaria and replanting with native species has resulted in dune reprofiling. This has allowed Chatham Island oystercatcher Haematopus chathamensis, an endangered species, to nest higher up the beach where they are less vulnerable to loss of clutches to high tides and storm surges.

A 50 ha degraded mine spoil area in the English Midlands was, covered with top-soil, re-seeded, and native deciduous trees and shrubs were planted. Carabid beetle species richness and diversity tended to increase with time after planting, and afforestation increased carabid species richness. The species composition of the ground flora appeared to have little effect on carabid distribution.

Restoration and creation of footdrains on grazing marshes in eastern England improved breeding habitat quality for lapwing Vanellus vanellus and redshank Tringa totanus, two wader species declining in numbers throughout lowland England. In particular, they provided increased foraging habitat for these wader chicks which prefer to forage around the invertebrate-rich margins of the footdrains. Numbers of breeding lapwing and redshank have increased dramatically, and wintering waders, ducks and geese have also benefited.

In the Highlands of Scotland, low intensity burning would appear to be an effective way to encourage Scots pine Pinus sylvestris regeneration. As well as opening up the ground allowing seedlings to grow, low to moderate burns had no major impact on ectomycorrhizal communities; without a healthy ectomycorrhizal community pine seedlings struggle to become established.

The twite Carduelis flavirostris, is a small finch which has undergone serious declines in the UK. In the Pennine Hills, northern England, feeding stations were established as a stop-gap prior to instatement of 'twite-friendly' meadow-management to try and bolster breeding twite populations. Despite presence of a nearby source of seed supplied at a feeding station, breeding twite utilised seeds of wild plants to feed there chicks. However creation of the feeding station adjacent to a twite breeding colony, judging by the number of visiting birds, appears to benefit them by providing pre- and post-breeding food sources. Birds from other breeding colonies in a 20 km radius were also recorded using the feeding station.

In the Pennine Hills, northern England, feeding stations were established as a stop-gap prior to instatement of 'twite-friendly' meadow-management to try and bolster breeding twite populations. As at another feeding station, despite supplying seed close to a breeding colony, twite utilised seeds of wild plants to feed there chicks.

The twite Carduelis flavirostris, is a small finch which has undergone serious declines in the UK. In the Pennine Hills, northern England, feeding stations were established as a stop-gap prior to instatement of 'twite-friendly' meadow-management to try and bolster breeding twite populations. Unlike two other feeding stations in the Pennines that attracted many twite in the pre- and post-breeding periods, twite utilised the feeding station rarely and only in very small numbers. If placed closer to natural feeding areas in may have promoted greater usage. This small twite colony was also situated in an outlying area, whilst the two other stations were along local migration routes, again perhaps accounting for the paucity of use. Careful siting of feeding stations is therefore required, based on foraging areas already known to be utilised and preferably in areas where pre- and post-breeding flocks gather.
