Supplementary Material 1 – Plant life form classification. Plant life form classification sensu Raunkaier is a simple but still useful way of functionally classifying plants.

A more detailed way is given under 2. Robert Whittaker described life form classification as follows Whittakerwith our modifications: Perennating tissue is what enables the plant to survive harsh, unfavorable cold or dry seasons.

For the purposes of this classification, perennating tissue comprises not only buds including those of specialized perennating organs mentioned in 2. Life history and maximum plant lifespanbut also formws.

Locating the perennating buds plantae the surface provides added protection from harsh-season conditions. For species that may be subject to disturbances, such as grazing and fire, the position of buds or bud-forming tissues allows us to understand the likelihood of their survival.

Supplementary Material 1 – Plant life form classification

The definitions given below refer to the highest perennating buds for any particular plant. Life form is a categorical trait assessed from field raunnkiaer, descriptions or photos in the literature.

Many floras give life forms as standard information on plant species. Five major life forms were initially recognised by Raunkaier; his scheme was further expanded by various authors. Here we give a simple, only slightly modified scheme SM 1 – Fig.

Aquatic plants that perennate from a bottom-dwelling organ such as a rhizome or tuber but whose shoots emerge, and display their leaves, above the water surface during the growing season, are termed emergent hydrophytes or helophytes Greek helos, marsh, see f Helophytes below.

Bulb, corm and tuber-bearing plants, and those that perennate via subsurface rhizomes, are geophytes. These plus hydrophytes are collectively termed cryptophytes, because their perennating organs are hidden from aerial view.

Prostrate subshrubs, perennial cushion and rosette forms see 2. Growth form and plants perennating by rhizomes that grow on the ground surface, are all hemicryptophytes. Dwarf shrubs, and most tussocks, would be classified as chamaephytes.

Climbers and epiphytes would be classified, along with shrubs and trees, as phanerophytes since they normally extend, or occur, more than 0. Therophytes include not only annuals, but also monocarpic perennials c. Life history and maximum plant lifespan which, however, for the seasons prior to their seed reproduction, must fall into one of the other life-form categories.
