This document discusses various vegetation sampling techniques, including those using plots and those without plots. Techniques using plots include the quadrat method, species area curve method, and methods using multiple plots arranged systematically or randomly. Techniques without plots include point intercept, line intercept, and distance methods which measure distances between plants rather than using defined plots. The document provides details on how to implement several of these techniques and notes they allow efficient, low-cost sampling of vegetation characteristics.

- 6. Defenition The technics use to measure, to know, to get information about a vegetation with fast, easy, less need money, and less need energy. Because we just take some data to represent all data in a vegetation Diferent with Sensus method We must take all of data information about a vegetation and that must invetarisation

- 13. METODE SPECIES AREA CURVE (MINIMAL AREA) The technics with plot where, we must see the LUAS TERKECIL that represent all of a vegetation characteristic
- 14. METODE KUADRAT The sampling technics like square or cycle with a wide that support by vegetation form Type Base on sum of plot Single plot Multiply plot others Metode jalur/transek Metode garis berpetak Metode kombinasi
- 15. Single plot Make one sampling plot with a size that represent a TEGAKAN The Plot size can make with species area curve method The plot can devide into small plot again usually for homogen information vegetation
- 16. Multiply plot Use many plot that in area will observe The plot can arrange with sistematis or random
- 18. Metode garis berpetak Modification of technic from multiply plot or jalur method that jump of plots in jalur rintis make the plot and another plot have same distance. 20m x 20m : trees 10m x 10m : poles 5m x 5m : sapling 2m x 2m : seedling/ tumbuhan bawah.
- 19. Metode kombinasi This method is combination between jalur method and line with plot Trees can measure with jalur method with wide 20 m And for poles, sapling, seedling use line with plot method
- 20. Without plot method At the basic concept, this technics use the measure of distance between one plant and anothers plant that have small distance that mean the vegetation is re-peattedly Some advantages : save the time decrease of mistake when make the sampling Decrease of mistake when we say the plant at inner place or outer place
- 21. Metode Point Intercept (Metode Titik Sentuh) Special for herba plant that very rough arrangement Use the point frecuency frame and quadrat point tools The process, with write the plant that first touch by pin of tools How use the point intercept methods? Choose the vegetation we will observe Take the point frecuency frame tools with re- peattedly Write the first plant that have been pin
- 22. Metode Line Intercept (Metode Garis Sentuh) Agree with determine the cover and frecuency at perdu layers Transek change with line form All of tajuk daun that struck by the line must measure the length If the line use 100 m size, so the cover is per 100 m So, if we use the point intercept methods and line intercept methods will get 2 parameters, such as : Cover frecuency
- 23. Metode Point-Centered Quartered Special for trees vegetation measure this methods so easy to get information about trees, aspecially for kinds composition, Dominancy level, menaksir trees volume Character this methods, the trees must in random distribution arrange Make one point at centre and some imagination line that make 4 quadran Chooce one trees for each quadran that near with point and measure the distance between trees and point And measure the braest high of trees
- 24. Distance Method (Metode Jarak) Can measure the 3 parameters, such as : cover, frecuency and density Sum of individu can determine with measure distance between for each individu or between sampling point and plant By Grant Cottam dan John Curtis from wisconsin univercity at 1950-an Metode individu terdekat (nearest individual method) Metode titik pusat kuadrat (point-centered quarter method) Metode tetangga terdekat (nearest neighbor method) Metode berpasangan acak (random pairs method)
