Frame quadrats can be used to determine plant density (counting individuals in a m² quadrat), frequency (percentage of grids containing a species), and percentage cover (estimated area covered by a species).
يمكن استخدام مربعات القياس المربعة لتقدير كثافة النباتات، وتحديد تكرار الأنواع (نسبة مربعات القياس التي تحتوي على النوع)، وتقدير النسبة المئوية لغطاء الأنواع بالعين.

|---|---|
| Back | - density (if individual large plants seen, count number of them in 1m by 1m quadrat giving you density (m2) and is not estimate (unlike following 2) - frequency (used if individuals hard to count, use small grids on quadrat and see % of grids this species fill) - % cover (used for speed as lots of data collected quickly, useful for abundant species, estimate by eye of area within quadrat covered by species) |
