field work Flashcards
HW
3 hazards, their risks and what actions were taken to avoid them
- Brambles - cuts, scratches - wear long sleeves, avoid hazardous plants
- Insects - Tick bite (lyme disease) - long sleeves and check for bugs when home
- Weather (sun/rain) - sunstroke/hyperthermia - dress appropriately
HW - data collection method of quantitative data and its effectiveness
tallies of number of species in each forest layer
allowed us to calculate the Simpsons biodiversity index and so we could draw graphs and conclusions on how biodiversity differed
HW - data collection method of quanlitative data and its effectiveness
photos, sketches
- gave a visual reminder of the area
- could also use photos to compare to old photos and conclude whether management strategies were working
HW - data collection method using sampling and what was it used for
quadrat sampling method
- could collect the type and number of species, to calculate biodiversity
HW - data presentation methd for quantitative data ,what did it show and why was it effective
Bar graph
- showed the different levels of biodiversity on the forest floor
- easy to create and analyse
HW - data presentation method for qualitative data what did it show
annotated map - could display the data of different sites in a descriptive and visual way
HW - satistical data presentation method
Simpsons biodiversity index helped clearly show the different levels of biodiversity in each site
HW - biodiversity of mature tree canopy layer
8.6
HW - biodiversity of shrub layer
2.8
HW - example of a management strategy, is it effective (+ however..) + evidence
cutting down conifer plantation to allow native species to grow
- strategy is working well <– high biodiversity in canopy layer (8.6) also 11 species of native trees
- however more trees means lower biodiversity in shrub layer (2.8)
HW - What had taken place in site 1 to allow high biodiversity
**secondary succession - ** when animals and plants recolonise an area that experienced a disturbance
allows more native species to grow
HW - why was it lower biodiversity in site 2
due to the pine needles which fall from the trees and don’t decompose, minimising the nutrient cycle
also the tall trees reduce sunlight available to the lower layers
HW - management strategy to improve nutrient cycle in site 2
logs and twigs are left to rot so nutrients cycle can successfully take place
HW - why were some conifer trees left to stand
to act as a windbreak in order to protect the rest of the woodland
HW - management strategy to increase bird population
bird boxes attached to many trees which provides a safe space for birds to live and have chicks
