Quadrats are used for sampling plants and slow-moving animals. Point and frame quadrats measure density, frequency, and percentage cover, and are typically used after random sampling or systematically along transects.
تُستخدم مربعات القياس لأخذ عينات من النباتات والحيوانات بطيئة الحركة. تشمل الأنواع مربعات قياس نقطية ومربعة، والتي تُستخدم لقياس الكثافة والتكرار والنسبة المئوية للغطاء.
