Representative species by floral zone

edit

Doi Suthep–Pui National Park displays altitudinal zonation. This section lists some of the characteristic species of each floral zone.[1]

Bamboo/deciduous seasonal forest

edit

Of the 173 tree species which occur in bamboo/deciduous forest, 125 (72%) are deciduous and 31 are common or abundant.

Trees that are commercially valuable include:

Other characteristic trees are:

A total of 316 herb species has been recorded in bamboo/deciduous forest, of which 294 are ground herbs. Of those, 65% are perennial.

Deciduous dipterocarp-oak seasonal forest

edit

In seasonally dry or degraded areas, from the lowlands up to about 800-900 m elevation, deciduous dipterocarp-oak forest replaces bamboo/deciduous forest. It is a secondary, fire climax forest which merges with bamboo/deciduous forest, but is never replaced with mixed evergreen/deciduous forest.

It contains less biodiversity with only 99 tree species, of which 24 are common or abundant.

Dominant tree species of the Dipterocarpaceae include:

Common Fagaceae species include:

Other characteristic trees are:

Additional common species:

2 tree species have rapid leaf turnover, flushing new leaves at the same time as the old leaves are shed. They include:

The following tree is very common at higher elevations (650-800 m), along with the two trees listed above:

Deciduous dipterocarp-oak forest supports only 14 species of woody climbers, but the deciduous species that are easily found are:

Shrubs (29 species) and treelets (48 species) are abundant. Some common examples are:

Mixed evergreen/deciduous seasonal forest

edit

From about 800 m elevation (600 m near permanent streams) to about 1000 m, there is a mixture of deciduous and evergreen trees.

217 tree species have been recorded, with only about 43% of them being deciduous trees. The tree flora is similar to that of the bamboo/deciduous forest.

The characteristic tall, emergent, evergreen, dipterocarps, which have large gray trunks, small leaves, and open, broad crowns, are:

In contrast, the deciduous dipterocarp-oak forest has large-leaved dipterocarps.

Typical ferns include:

Primary evergreen seasonal forest (without pine)

edit

The upper part of the mixed evergreen/deciduous forest usually merges with the lower part of the evergreen forest at c. 900-950 m elevation.

Evergreen forest supports more tree species than any of the other forest types. 250 species have been recorded, of which only 67 (27%) are deciduous.

The evergreen forest has a wide variety of trees, with no dominant species or genera. Trees belong to diverse families, such as Lauraceae, Fagaceae, Theaceae, Moraceae, Magnoliaceae, and other families.

Characteristic evergreen canopy trees include:

Several gigantic "strangling" figs:

Characteristic Fagaceae species are:

Castanopsis spp. tend to be shared with other forest types, including:

Other characteristic evergreen trees include:

A few of the larger deciduous canopy species include:

Most also occur in the deciduous forest types.

Some of the deciduous trees which are restricted to evergreen forest are relatively rare, including:

Other deciduous trees more typical of deciduous forest types sometimes spread up into evergreen forest due to fires or human disturbance. Common tree species shared with other forest types include:

The understory is denser than that of forests at lower elevations and is especially diverse in stream valleys. Understory trees include:

Primary evergreen seasonal forest (with pine)

edit

On fire-prone, exposed ridges at elevations of about 950–1,800 m, Pinus kesiya grows together with other evergreen forest tree species. In some areas, it is the dominant tree.

Some species more commonly found with Pinus kesiya than elsewhere, mostly due to the acidic lower pH of the soil, include:

Where fires are particularly frequent, plants of deciduous dipterocarp-oak forest spread up into the pine forests at much higher elevations than is typical, including:

In such areas, trees of the Fagaceae family are also common, including:

Altogether 99 tree species have been recorded, of which only 27 (27%) are deciduous.

Summit flora

edit

The summit flora has been significantly altered, especially after the original primary evergreen forest was cleared and replaced with cultivated trees on the summit of Doi Pui in 1955. The soil has also become much more acidic.

Some of the original epiphytic flora has returned to the summit of Doi Pui, such as:

Some evergreen herbs which have returned, albeit in diminished populations, include:

Deciduous herbs are more common, including:

9 plant species, all of which are rare or down to a few individuals, are entirely restricted to summit areas between 1620 and 1685 m above sea level. They are:

However, several species have disappeared from the summit:

Mountains in Thailand that more or less preserve the original vegetation at above 1650 m are Doi Inthanon (2565 m), Doi Chang (1975 m), and Doi Lang Ka (2031 m).

Disturbed areas and secondary growth

edit

A total of 288 species of ground herbs survives in disturbed areas or secondary growth. 144 species are annuals, and 144 species are perennials. There are numerous annual tertiary growth herbaceous weeds, all of which require exposure to sunlight for germination and growth. Some of the more common species found at all elevations include:

Monocot weeds are also diverse and abundant. Some common examples are:

Robust perennial grasses are especially common in upland areas. They are robust, evergreen, and very persistent weeds in open, fire-damaged, upland areas, and include:

Naturalized woody weeds that often dominate open, disturbed areas are:

Secondary growth treelets (36 species) and trees (81 species) are common seen. If left undisturbed, they are replaced by primary forest trees. Some typical examples are:

In human settlements

edit

Common shade trees include:

Some flowers and shrubs are:

Medicinal plants:

Exotic ornamental plants:

Plants species with large, colourful inflorescences, which have now escaped cultivation and are extirpating native species:
