  2. Pin-point method (ecology) - Wikipedia

    en.wikipedia.org/wiki/Pin-point_method_(ecology)

    The pin-point method (or point-intercept method) is used for non-destructive measurements of plant cover and plant biomass. [1] [2] In a pin-point analysis, a frame (or a transect) with a fixed grid pattern is placed above the vegetation. A pin is inserted vertically through one of the grid points into the vegetation and will typically touch a ...

  3. Tree allometry - Wikipedia

    en.wikipedia.org/wiki/Tree_allometry

    Stem profile measurement Electronic equipment (as Field-Map for example) is used for stem profile measurements and for measurements of profiles/projections of the crown. These key measurements are used for estimation of carbon sequestered in the plants. Forest structure measurement is needed for establishment of allometric equations.

  4. Tree crown measurement - Wikipedia

    en.wikipedia.org/wiki/Tree_crown_measurement

    In forestry, a tree crown measurement is one of the tree measurements taken at the crown of a tree, which consists of the mass of foliage and branches growing outward from the trunk of the tree. The average crown spread is the average horizontal width of the crown, taken from dripline to dripline as one moves around the crown.

  5. Process flow diagram - Wikipedia

    en.wikipedia.org/wiki/Process_flow_diagram

    A process flow diagram (PFD) is a diagram commonly used in chemical and process engineering to indicate the general flow of plant processes and equipment. The PFD displays the relationship between major equipment of a plant facility and does not show minor details such as piping details and designations.

  6. Biomass (ecology) - Wikipedia

    en.wikipedia.org/wiki/Biomass_(ecology)

    Changes in plant species in the terrestrial ecosystem can result in changes in the biomass of soil decomposer communities. [13] Biomass in C 3 and C 4 plant species can change in response to altered concentrations of CO 2. [14] C 3 plant species have been observed to increase in biomass in response to increasing concentrations of CO 2 of up to ...

  7. Piping and instrumentation diagram - Wikipedia

    en.wikipedia.org/wiki/Piping_and_instrumentation...

    Piping and instrumentation diagram of pump with storage tank. Symbols according to EN ISO 10628 and EN 62424. A more complex example of a P&ID. A piping and instrumentation diagram (P&ID) is defined as follows: A diagram which shows the interconnection of process equipment and the instrumentation used to control the process.

  8. Biomass partitioning - Wikipedia

    en.wikipedia.org/wiki/Biomass_partitioning

    Biomass partitioning is the process by which plants divide their energy among their leaves, stems, roots, and reproductive parts.These four main components of the plant have important morphological roles: leaves take in CO 2 and energy from the sun to create carbon compounds, stems grow above competitors to reach sunlight, roots absorb water and mineral nutrients from the soil while anchoring ...

  9. Biomass - Wikipedia

    en.wikipedia.org/wiki/Biomass

    Biomass is a term used in several contexts: in the context of ecology it means living organisms, [1] and in the context of bioenergy it means matter from recently living (but now dead) organisms. In the latter context, there are variations in how biomass is defined, e.g., only from plants, [ 2 ] from plants and algae, [ 3 ] from plants and ...
