Holyford Woods Flashcards
What is the fieldwork question for Holyford Woods?
“management strategies attempt to maximise biodiversity in Holyford Woods”
What are the Hazards of Holyford Woods? Who are at risk for these?
- Brambles, nettles and insects
- Weather: rain, wind, sun
- Steep sided areas, uneven grounds
RISK= STUDENTS AND TEACHERS
How are Brambles, nettles and insects a risk?
Cuts, thorns, allergic reactions, poisoning
Insect bites + scratches-> ticks= Lyme’s disease
How is the Weather (rain, wind, sun) a risk?
Hypothermia
Sunstroke
How are Steep sided areas/uneven grounds a risk?
Slips and trips
Falling + bruising
Broken/twisted limbs and bones
What is the likelihood of these risks?
LOW RISK
What is the proposed action to prevent risk of Brambles, nettles and insects?
Wear long sleeves + long trousers-> avoid risk
Identify hazardous plants to others and warn potential risks
Avoid sitting in long grass + check skin for ticks at home
What is the proposed action to prevent risk of weather (rain, sun, wind)?
All children receive information asking them to be dressed appropriately for the weather conditions
Bring water + suncream
What is the Proposed action to prevent risk of steep sided areas + uneven grounds?
Ensure all students and teachers are wearing appropriate footwear + sturdy boots + wellington boots
Warn participants of hazard at the beginning and throughout activity
What is the landscape of Holyford woods like?
North side
- oak + ash trees
- holly, hazel, hawthorn, birch
South side
- conifers planted in 1960’s by owners at the time, South West Water
Animals
- dormice
- insects, bats, deer, foxes, badgers, woodpeckers
What is Primary Succession?
When a new area of land is populated by a group of species for the first time
What is Secondary Succession?
When an area of land previously occupied by living species goes though a major disturbance, and repopulates
Where did secondary succession occur in Holyford woods?
Site 1- cleared area
What were the methods used to collect data?
- Vegetation survey: tree and shrub layer
- Vegetation survey: field and ground layer
- Annotated sketches
- Photographs
What were the Primary Quantitative methods of data collection?
- Counting number and variety of species in deciduous woods
- Used 50cm x 50cm quadrats with 6 different groups
- Used 20cm x 20cm quadrats for shrub layer
Used Simpson’s biodiversity index
What were the methods of Primary Qualitative data collection?
- Took photographs
- Evidence of management
- Evidence of secondary succession
- Sketched
What were methods of Secondary data collection?
- Compared old photos to new photos to show how sites regenerated over time
- Compared to old data of how many different species and numbers of species with new data
What were the methods of data representation used for Quantitative data?
Pie charts
- easy to interpret and compare different sites and different species
What were the methods of data representation used for Qualitative data?
Photos and Sketches-> taken + annotated
What statistical method was used to represent biodiversity in the sites?
Simpsons biodiversity index
- See and calculate how biodiverse different areas of the woods are
What were the sampling methods used?
- 6 groups along a line used transects
- Used a large area to cover more area
- Threw quadrats randomly to avoid bias
What are the 3 guiding principles of woodland management?
Diverse
Connected
Native
What are the 3 sites surveyed?
- Cleared area (2005)- shrubs, not much diversity, sights of regeneration, secondary succession
- Conifer plantation- no diversity, no shrub layer, non native
- Deciduous woods- high diversity between all layers, native climax community
Why was Holyford woods a good location to choose?
3 sites-> diverse between them, all connected
Many management strategies have been put in place, can be seen
Local nature reserve-> easy access
