Quadrats provide a simple but effective scientific method for the ecological surveying of vegetation or invertebrates in a wide range of habitats.
Q1 Quadrat
The Q1 quadrat is strong and non-collapsible, made from heavy gauge steel wire with zinc plating - it is smooth, UV resistant and cannot be chipped.
Measures 0.5m x 0.5m and has no divisions. Suitable for general vegetation or intertidal surveying.
Q2 Quadrat
The Q2 quadrat is made from heavy gauge steel wire with plastic coating to protect welds and make the quadrat visible.
The 0.5m x 0.5m frame is subdivided into 25 squares for sampling dense vegetation or species-poor habitats. Each individual square measure 10cm x 10cm.
Q3 Quadrat
The Q3 quadrat is made from heavy gauge steel wire, with plastic coating which protect welds and makes the quadrat highly visible. The 0.5m x 0.5m frame is subdivided into 100 squares for calculating percentage cover, or making presence/absence recordings.
Q4 Quadrat
The Q4 Quadrat is a strong collapsible quadrat made from four pieces of heavy gauge steel wire with zinc plating. Ideal for travel, the Q4 is smooth, UV resistant and cannot be chipped.
A single Q4 frame will make a 0.5m x 0.5m open frame without divisions suitable for general vegetation survey. Additional units can be used together to make a variety of quadrats - i.e. 1m x 1m or 1m x 0.5m.
