Coarse pine bark mulch as open surface cover fails to improve establishment of sown native grasslands
This study was conducted across twelve agricultural locations in south-western Victoria, Australia, encompassing a range of soil types and climatic conditions. It investigated the addition of an open layer of coarse organic pine wood chip mulch (~70% surface cover) directly following direct seeding of native grassland species. The intent was to mimic positive effects of naturally occurring organic surface litter (which are typically depleted in such settings) on seedling emergence and establishment. Findings revealed negative results in that the use of an open layer of coarse pine chip mulch failed to improve native establishment at 12-months or to moderate soil temperature and moisture extremes in comparison to non-mulched plots. This outcome suggests the effectiveness of open surface mulches under the scenario of direct seeding may be highly site context, mulch-type, and application approach dependent. In situations where such mulch applications are not likely to be beneficial, significant costs relating to their purchase and application could be avoided.
期刊介绍:
Ecological Management & Restoration is a peer-reviewed journal with the dual aims of (i) reporting the latest science to assist ecologically appropriate management and restoration actions and (ii) providing a forum for reporting on these actions. Guided by an editorial board made up of researchers and practitioners, EMR seeks features, topical opinion pieces, research reports, short notes and project summaries applicable to Australasian ecosystems to encourage more regionally-appropriate management. Where relevant, contributions should draw on international science and practice and highlight any relevance to the global challenge of integrating biodiversity conservation in a rapidly changing world.
Topic areas:
Improved management and restoration of plant communities, fauna and habitat; coastal, marine and riparian zones; restoration ethics and philosophy; planning; monitoring and assessment; policy and legislation; landscape pattern and design; integrated ecosystems management; socio-economic issues and solutions; techniques and methodology; threatened species; genetic issues; indigenous land management; weeds and feral animal control; landscape arts and aesthetics; education and communication; community involvement.
