Long Questions Flashcards
Continuous Cover Forestry (CCF) is a forest management approach suitable to both
conifers and broadleaves. Can you list 3 advantages to adopting CCF against
convectional clear-fell system? And elaborate your understanding of CCF.
CCF allows for the production of commercial timber while retaining a forest cover at all times. It often relies on harnessing natural Forest processing such as natural regeneration of trees, mixed tree species, increased biodiversity and natural fprest development (forest succession). It is also known as Close-to-Nature Forest management.
Compared to Clear Fell system where all trees are harvested and then replaced at the end of the rotation, CCF offers the possibility to harvest a similar timber volume over the same period of time but in regular intervals (3-6 years) and without any loss of Forest Cover.
Advantages: CCF management aims to work with the natural life cycle of Forests, maximising both productivity and is achieved by carrying out cyclical thinning. Thining can be applied either uniformly over the Forest or in groups according to the Forest development stage and tree species characteristcs. CCF encompasses a number of silvicultural system(such as selection and shelterwood systems) each suited to different circumstances.

Ecology habitats and biodiversity – can you describe biodiversity and what it means to you
and give examples in a farm forestry context were biodiversity and habitat are offered
protection, please demonstrate you knowledge to what plants, birds, insects, mammals
that would occupy this created environment. (10 marks)
Biodiversity comprises everything that grows and lives on a farm eg livestock, crops, insects, trees, plants and animals). A group of plants and animals living together is known as a community and where they live is their habitat. A community and habitat form an ecosystem eg a forest.
In a farm forestry context, areas for Biodiversity enhancements offer protection to habitats and biodiversity. They include environmental setbacks, retained habitats and future operational areas for future loading bay or roads. They conserve existing habitats and biodiversity features while promoting further diversity. A minimum of broadleaf component is also required on all new planting sites.
Planted forests benefit biodiversity by providing conditions suitable for a range of species and by facilating habitat connectivity within a landscape. Newly planted forests are rapid;y colonised after planting by a range of different woodland animals, birds and invertebrate species once the forest is connected to existing forests or hedgerows.
Insects provide food to birds and mammals. These include ladybirds.
Mammals include bank vole, wood mice, rats and mice, pine martens, pygmy shrews, hedgehogs, bats, red and grey squirrels, rabbits, mountain hares, foxes, badgers, mink, otters and deer.
Plants include
There are 4 Species of Deer in Ireland, can you name at least 2 of these and elaborate on
the damage and affects that Deer have on the Irish Forestry Industry and what control or
protection measure can be implemented to somewhat alleviate these?
Red Deer (Native), Fallow, Sika and Muntjac (Introduced)
Deer use forests for shelter, cover and grazing. Deer can jump to great heights so good
fencing is necessary to prevent them gaining access to a Forest. Deer fencing needs to be at
least 2m in height.
When establishing a Forest in a highly populated area for Deer, the owner should plan in
advance and consider planting trees that are less palatable to the deer.
In areas with high deer populations, the opportunity cost associated with planting
broadleaves is much higher. This is due to the cost of fencing, plant protection and replacing
damaged trees.
Deer can affect trees throughout the rotation of the forest. Deer will browse newly planted
trees until they reach a height where the stems and new shoots are beyond the reach of the
Deer.
Alternatively, Deer can strip and eat the bark of the trees which leads to butt rot and serious
financial losses to the forest owner.
Bark Stripping occurs primarily during the spring period before fresh growth occurs and in
the summer when sap is rising and the bark is softer.
During the breeding season, deer can cause damage to the trees with their antlers (known
as fraying)
Soft, smooth-barked trees are most likely to be damaged e.g. Beech, damage will normally
occur on the stem between 0.75-1.75m from the ground.
Control measure: Appropriate Deer Fencing, Species Selection, Culling (Shooting), Tree
Guards
Thinning is a Harvest Management Practice, explain what is meant by Thinning a Forest
and what are the main benefits associated with Thinning? When might Thinning be
considered to not be an option on Forestry site? (
Thinning is the removal of a proportion of the trees in a forest. It is carried out to provide
more growing space for the remaining trees and to provide timber and income before final
harvest. If a percentage of trees are removed at various stages during the life of the forest,
the remaining trees have more growing space, resulting in fewer trees but will be of greater
quality and size.
Benefits of Thinning:
1. Forest Premium running out- provide a periodic
2. Salvage material that will ultimately die
3. Provide increased growing space for trees
4. Remove less valuable material in Thinning
5. Maximise productive potential of site – increase by 10%
6. Increase revenue returns-Thin vs. No-Thin
7. Provide improved access to and through the Forest
8. Increase biodiversity within the Forest (grass etc.)
The first decision to be taken is whether to thin or not to thin the Forest. In some cases
following assessment and consideration, the option may be too thin earlier or not thin at all.
Thinning may not be an option where the site:
1. Very exposed , and/or very wet
2. Has restricted access
3. Is not economically viable
4. There is a significant risk or site is prone to wind throw

The theme – the Strengths, Weaknesses, opportunity and threats (S.W.O.T)
analysis on establishing a farm forestry enterprise;
A SWOT analysis (Strengths, Weaknesses, Opportunities, and Threats) is a strategic tool used to evaluate the internal and external factors that could influence a business or project. In the context of Irish farm forestry, this framework helps farmers and landowners assess their forestry operations more effectively and make informed decisions.
Here’s how a SWOT analysis would apply to Irish farm forestry:
- Natural Resources: Ireland’s climate is ideal for certain types of trees, such as Sitka spruce, which grow well in the temperate, wet environment.
- Biodiversity: Forestry can enhance biodiversity on the farm by creating habitats for wildlife.
- Government Support: There are strong financial incentives and grants for farmers to engage in forestry in Ireland, including afforestation schemes.
- Sustainability: Forestry can increase the long-term sustainability of the farm by creating a diversified income stream, sequestering carbon, and improving soil quality.
- Long-Term Investment: Trees take many years to mature, meaning income from timber can take decades to materialize. This may be a challenge for farmers who need quicker returns.
- Complex Regulations: Navigating the regulations around forestry can be difficult for farmers who may not be familiar with forestry management practices and legislation.
- Land Use Trade-offs: Dedicating land to forestry could mean less space for traditional agricultural activities, which could reduce overall productivity or limit diversification opportunities.
- Skill Requirements: Managing a forest requires specialized knowledge in forestry practices, tree species, pest control, and harvesting, which might be outside the farmer’s expertise.
- Timber Market: The demand for timber is growing globally, especially in construction and renewable industries, which could provide a lucrative market for Irish farm foresters.
- Agroforestry Practices: Farmers can integrate forestry with traditional agriculture (e.g., agroforestry), which offers both environmental and economic benefits.
- Carbon Credits and Climate Change Mitigation: With an increasing focus on climate change, farmers could benefit from carbon credit schemes by planting forests that sequester carbon.
- Diversification: Forestry allows farmers to diversify their income streams, reducing reliance on traditional crops or livestock.
- Market Volatility: Timber prices can fluctuate based on international demand and supply, which could impact profitability.
- Climate Change: While forests help mitigate climate change, changing weather patterns could also negatively affect tree growth or make forests more susceptible to pests and diseases.
- Pests and Diseases: Forestry operations are vulnerable to various pests and diseases that can damage trees and reduce timber quality.
- Public Perception: Some stakeholders may view the expansion of forestry negatively, particularly if they believe it impacts biodiversity, tourism, or local landscapes.
- Clearer Insights into Risks and Benefits: By categorizing the strengths and opportunities of farm forestry, as well as identifying weaknesses and threats, a SWOT helps farmers clearly understand the pros and cons of investing in forestry.
- Strategic Planning: SWOT allows farm forestry operators to develop strategies that capitalize on strengths and opportunities while mitigating threats and addressing weaknesses. For instance, if a farmer identifies climate change as a threat, they may opt to plant tree species more resilient to changing conditions.
- Prioritization of Resources: A SWOT helps allocate resources more effectively. A farmer can focus efforts on areas of strength (e.g., maximizing timber yield) while addressing key weaknesses (e.g., lack of knowledge about forestry regulations
