Learning Outcomes
On successful completion of this module students should be able to:
1. appreciate current thinking about the nature of plant communities within landscapes
2. employ the terms used in plant and community identification and be confident in the field identification of a range of plants and animals.
3. appreciate the need for biological recording schemes and devise appropriate sampling strategies and recommend sampling techniques for a range of species, habitats and circumstances.
4. undertake a community survey, present and analyze their data. Summarizing results to appropriate scientific standards.
Brief description
The module describes how plant communities are inter-related at the landscape scale. Within the landscape exists the basic matrix which includes patches of communities or complex mosaics. Both reflect the pattern of resources and constraints that occur within the landscape (in time and space). Landscapes can behave like "supersystems" and connectivity is important in their functioning. Populations of individual species may not be isolated, but form metapopulations which contribute to their stability. Changes in communities over time are considered looking at succession and "climax" vegetation. Human and natural phenomena affecting plant communities are considered and students will learn how to identify species and surveying skills in a range of contrasting Welsh habitats. Students will engage in five days of surveying skills during the Easter vacation. There will be no additional costs incurred but participants must organise their own accommodation.
Content
Changes in communities over time are considered. Communities are not static, but change, often in apparently predictable ways. They may be directed by the sequence of species present (autogenic), or driven by environmental conditions that change over time (allogenic). The resource-ratio hypothesis has been suggested as the mechanism for "climax" vegetation, but multiple end points of change are evident within many areas.
Both human and natural phenomena affecting plant communities are considered. Grazing animals may show a high incidence of specialisation in shaping the composition of plant communities while fire naturally causes biomass removal in many landscapes. Human use may represent simple biomass removal, as in hay regimes, alternatively, it may be selective removing particular species or particular groups of individuals (such as a size class) for a particular use, thereby affecting the community. The description of plant communities and their distribution in space is discussed based on both numerical (ordination and classification) and descriptive phytosociological (represented by NVC) approaches.
For developing practical experience the students will be expected to :
i) Conduct a small mammal survey from week eight onwards: this will involve trapping and assessing small mammal populations locally.
ii) Undertake a local five day field course (during the Easter vacation). The aim is to establish expertise in plant species identification in a range of contrasting Welsh habitats including hedgerows and deciduous woodlands.
Students will receive guidance and instruction on the various techniques available for sampling and population assessment strategies (plants and animals). They will also describe communities and will look at soil characteristics.
