He applied the same mathematical formula to describe plant size over time. The equation for exponential mass growth rate in plant growth analysis is often expressed as: = Where: M(t) is the final mass of the plant at time (t). M 0 is the initial mass of the plant.
Phoenix sylvestris ranges from 4 to 15 m in height and 40 cm in diameter; not as large as the Canary Island Date Palm, but nearly so, and resembling it. The leaves are 3 m long, gently recurved, on 1 m petioles with acanthophylls near the base. The leaf crown grows to 10 m wide and 7.5 to 10 m tall containing up to 100 leaves.
Phoenix is a genus of 14 species of palms, native to an area starting from the Canary Islands in the west, across northern and central Africa, to the extreme southeast of Europe , and continuing throughout southern Asia, from Anatolia east to southern China and Malaysia. [3]

Phoenix dactylifera, commonly known as the date palm, [2] is a flowering-plant species in the palm family Arecaceae, cultivated for its edible sweet fruit called dates. The species is widely cultivated across northern Africa , the Middle East , the Horn of Africa , Australia , South Asia , and California . [ 3 ]
P. sylvestris may refer to: Phoenix sylvestris , the silver date palm or sugar date palm, a flowering plant species Pinus sylvestris , the Scots pine, a pine species native to Europe and Asia
The formula can be read as follows: the rate of change in the population (dN/dt) is equal to growth (rN) that is limited by carrying capacity (1 − N/K). From these basic mathematical principles the discipline of population ecology expands into a field of investigation that queries the demographics of real populations and tests these results ...
Plant density is defined as the number of plants present per unit area of ground. In nature, plant densities can be especially high when seeds present in a seed bank germinate after winter, or in a forest understory after a tree fall opens a gap in the canopy.
