Misti volcano which overlooks Arequipa Arriving into Arequipa at 6: I was absolutely shattered, along with Tom Wilkes from Sheffield. Nevertheless, head up we did with some Chilean collaborators the two Felipes! A brief stop to have a shower and then off we went in our rented, and as I was about to find out entirely necessary, 4 by 4.

Rare None If you are comparing more than one site, some plants could be totally absent Fieldwork number 1 some samples, so can be recorded as N for NONE. Many investigators over-estimate conspicuous plants especially those in flower and under-estimate inconspicuous plants.

More reliable data will come from quantitative methods. The simplest way to collect data using a frame quadrat is to make a species list for each quadrat.

This allows you to calculate the percentage frequency of each species for the whole sample area. Percentage frequency is the probability that a species will be found within a single quadrat. For example, an investigation was made into the difference in vegetation between a grazed and an ungrazed section of the fixed dunes.

A random sample using 30 frame quadrats is taken in each area. In the grazed area, bird's-foot trefoil was present in 18 of the 30 quadrats; in the ungrazed area, bird's-foot trefoil was present in 6 of the 30 quadrats. The number must be large enough to minimise the effect of anomalies, but not too large that it cannot realistically be carried out in the time available.

In practice, 10 quadrat samples is the absolute minimum for each sample area. There are two ways of describing the amount of each species within a frame quadrat: Percentage cover is faster but is more subjective. Simply estimate what percentage of the area enclosed by the quadrat is occupied by each species.

One drawback of this method is that plants in flower tend to be over-estimated while low-growing plants are under-estimated.

Local frequency is easiest to measure if you have a gridded quadrat of 10 x 10 squares. For each species, count the number of squares which are at least half-occupied.

The final figure which will vary between 1 and is the local frequency. This method is more time consuming than estimating percentage cover, but the results should be more accurate, as there is less risk of over-estimating some plants and under-estimating others.

The bar of the T has ten holes in it, and to sample vegetation a long pin much like a knitting needle is stuck through each hole. The different plants that the pin 'hits' as it is pushed towards the ground are identified and counted.

To collect data on abundance, count the first hit made by the pin on each different plant. Count the first hit only. Local frequency can be calculated for each species.

This shows what percentage of plants at each station are from each community. Shape of sand dunes To measure the angle of a slope between two points, you need two or three people.

Choosing a fieldwork location

Identify a slope unit between two breaks of slope. Person A stands at the bottom of the slope with the clinometer resting on top of a ranging pole. Person 8 holds a second ranging pole at the top of the slope. Person A sights the clinometer at the top of the ranging pole held by 8 and reads off the slope angle.

The distance and angle can then be recorded.For anthropologists, doing fieldwork is a kind of rite of passage, a process of initiation into the profession as well as a marker which separates anthropologists from other social scientists who "don't do fieldwork".

But one evening a fellow expatriate tips him off to a story: a charismatic American anthropologist. Everything you love about Louisiana Public Broadcasting - on the go! Watch LPB online! We ascended on winding gravelly roads, quickly reaching altitudes of > metres.

A level we would stay at for some time.

Climate Change Indicators

We passed frequent herds (?) of llama and alpaca (and the other two types whose names escape me) and some very small mountain villages before emerging onto an incredible sight (see photo) a plateau containing, if I recall correctly, a saline shallow lake.

The geography fieldwork investigation is assessed in Component Fieldwork requirements. All students are required to undertake fieldwork in relation to processes in both physical and human geography.
