Subalpine Meadows of Mount Rainier • an Elevational Zone Just Below Timberline but Above the Reach of More Or Less Continuous Tree Or Shrub Cover
Sub-Alpine/Alpine Zones and Flowers of Mt Rainier Lecturer: Cindy Luksus What We Are Going To Cover • Climate, Forest and Plant Communities of Mt Rainier • Common Flowers, Shrubs and Trees in Sub- Alpine and Alpine Zones by Family 1) Figwort Family 2) Saxifrage Family 3) Rose Family 4) Heath Family 5) Special mentions • Suggested Readings and Concluding Statements Climate of Mt Rainier • The location of the Park is on the west side of the Cascade Divide, but because it is so massive it produces its own rain shadow. • Most moisture is dropped on the south and west sides, while the northeast side can be comparatively dry. • Special microclimates result from unique interactions of landforms and weather patterns. • Knowing the amount of snow/rainfall and how the unique microclimates affect the vegetation will give you an idea of what will thrive in the area you visit. Forest and Plant Communities of Mt Rainier • The zones show regular patterns that result in “associations” of certain shrubs and herbs relating to the dominant, climax tree species. • The nature of the understory vegetation is largely determined by the amount of moisture available and the microclimates that exist. Forest Zones of Mt Rainier • Western Hemlock Zone – below 3,000 ft • Silver Fir Zone – between 2,500 and 4,700 ft • Mountain Hemlock Zone – above 4,000 ft Since most of the field trips will start above 4,000 ft we will only discuss plants found in the Mountain Hemlock Zone and above. This zone includes the Sub-Alpine and Alpine Plant communities.

Biodiversity Data Journal 2: e1019. doi: 10.3897/BDJ.2.e1019 Abstract The flora of Tropical Asia is among the richest in the world, yet the actual diversity is estimated to be much higher than previously reported. Myanmar and Thailand are adjacent countries that together occupy more than the half the area of continental Tropical Asia. This geographic area is diverse ecologically, ranging from cool-temperate to tropical climates, and includes from coast, rainforests and high mountain elevations. An updated checklist of aquatic plants, which includes 78 species in 44 genera from 24 families, are presented based on floristic works. This number includes seven species, that have never been listed in the previous floras and checklists. The species (excluding non-indigenous taxa) were categorized by five geographic groups with the exception of to reflect the rich diversity of the countries' floras.

Vascular Flora of Gus Engeling Wildlife Management Area, Anderson County, Texas
2003SOUTHEASTERN NATURALIST 2(3):347–368 THE VASCULAR FLORA OF GUS ENGELING WILDLIFE MANAGEMENT AREA, ANDERSON COUNTY, TEXAS 1 2,3 2 JASON R. SINGHURST , JAMES C. CATHY , DALE PROCHASKA , 2 4 5 HAYDEN HAUCKE , GLENN C. KROH , AND WALTER C. HOLMES ABSTRACT - Field studies in the Gus Engeling Wildlife Management Area, which consists of approximately 4465.5 ha (11,034.1 acres) of the Post Oak Savannah of Anderson County, have resulted in an annotated checklist of the vascular flora corroborating its remarkable species richness. A total of 930 taxa (excluding family names), belonging to 485 genera and 145 families are re- corded. Asteraceae (124 species), Poaceae (114 species), Fabaceae (67 species), and Cyperaceae (61 species) represented the largest families. Six Texas endemic taxa occur on the site: Brazoria truncata var. pulcherrima (B. pulcherrima), Hymenopappus carrizoanus, Palafoxia reverchonii, Rhododon ciliatus, Trades- cantia humilis, and T. subacaulis. Within Texas, Zigadenus densus is known only from the study area. The area also has a large number of species that are endemic to the West Gulf Coastal Plain and Carrizo Sands phytogeographic distribution patterns. Eleven vegetation alliances occur on the property, with the most notable being sand post oak-bluejack oak, white oak-southern red oak-post oak, and beakrush-pitcher plant alliances. INTRODUCTION The Post Oak Savannah (Gould 1962) comprises about 4,000,000 ha of gently rolling to hilly lands that lie immediately west of the Pineywoods (Timber belt). Some (Allred and Mitchell 1955, Dyksterhuis 1948) consider the vegetation of the area as part of the deciduous forest; i.e., burned out forest that is presently regenerating.
