The Oklahoma seaside alder (Alnus maritima ssp. oklahomensis) is a shrub that grows almost exclusively in Johnston County. While individuals resprout vigorously from rootstocks, few seedlings have been observed in the wild. We surveyed 1,848 one-meter- square plots of suitable microhabitat at two locations on the Blue River and a location on Pennington Creek. We found only 20 alder seedlings, all of them in their first year, and most of them in unsuitable, shaded conditions. These observations are consistent with the interpretation that, despite its abundant production of viable seeds, the Oklahoma seaside alder has effectively no long-term successful seedling establishment. These observations serve as a basis for seedling establishment experiments planned for the near future.

E. O. Wilson stated that invasive species are second only to habitat loss for reducing biodiversity, and that threat to biodiversity by invasive plants is the subject of this report. For that purpose, the standard definition of invasive species as one that causes harm to humans or other species when introduced to an ecosystem is too broad to be helpful. Under that definition, several native species are classified as invasive because they grow in cultivated fields, but biodiversity does not exist there.
E. O. Wilson指出，入侵物种是仅次于栖息地丧失的第二大生物多样性减少因素，而入侵植物对生物多样性的威胁是本报告的主题。出于这个目的，入侵物种的标准定义是，当入侵物种被引入生态系统时，会对人类或其他物种造成伤害，这一定义过于宽泛，没有帮助。根据这一定义，一些本地物种被归类为入侵物种，因为它们生长在耕地中，但那里不存在生物多样性。

Oklahoma is where several ferns reach their northern or eastern range limits. Among them are two species of lip ferns in the family Pteridaceae, Cheilanthes horridula Maxon and Cheilanthes lindheimeri Hook (Hoagland et al. 2007). C. horridula (prickly lip fern) is primarily found on dry limestone slopes in the Chihuahuan Desert region of northeastern Mexico. Its range extends northward to southwestern Oklahoma. C. lindheimeri Hook (fairy swords) is widespread in central and northern Mexico as well as the southwestern United States (Mickel and Smith 2004). In Oklahoma, the distributions of both are limited, and the numbers of individual plants of each species are likely to be relatively small, compared with other Oklahoma members of the genus Cheilanthes.

The following is a list of vascular plants of the redbed plains and gypsum areas of southwestern Oklahoma based on specimens collected by the author and deposited in the Oklahoma State Herbarium and the Bebb Herbarium of the University of Oklahoma. In addition, 26 taxa collected by previous workers and four observed, but not collected, are included and so indicated. Each taxon is listed alphabetically within its family and families are listed in order according to the Engler-Prantl classification scheme. Nomenclature originally followed that of Correll and Johnston (1970) and Waterfall (1969), but has been updated by Bruce Hoagland of the Oklahoma Biological Survey according to the National Plant Data Center, Baton Rouge, LA accessed January 2009.

The herbarium collections of the Wichita Mountains Wildlife Refuge have been transferred to the Cameron University Herbarium (CAMU) so that they could be safely curated, and electronically databased and still remain accessible to refuge personnel while for the first time becoming readily available to other interested researchers. This paper is a report on the initial inventory of the specimens. The 1784 specimen collection includes 101 families, 339 genera, and 634 species that have been physically repaired and taxonomically updated as needed, accessioned into the CAMU collections, and entered into the Specify Database.

Springtime brings a resurgence of greenery and wildflowers to the landscape. For those interested in fungi it is time to look for mushrooms as well. In Oklahoma spring mushrooms appear for approximately two to three-weeks from late March to mid-April.

The vascular floras of gypsum and redbed soils in southwestern Oklahoma were collected and studied during the growing season (April-October) of 1975. A total of 359 taxa and 230 genera and 63 families were included in the study. Thirteen taxa are considered to be gypsophiles and indicators of gypsum soils in Oklahoma. Nine taxa are considered calicoles occurring only on gypsum and limestone derived soils. Two introduced species, Bromus catharticus Vahl (syn. = Bromus willdenowii) and Caesalpinia gilliesii, are believed to be new additions to Oklahoma’s flora. Editor’s note: The abstract and a brief summary of this thesis was published as “Floristic Components of the Gypsum Hills and Redbed Plains Area of Southwestern Oklahoma” in The Southwestern Naturalist 24(3):431- 437 September 15, 1979 and is included here by permission.

Along the prairie/forest transition zone oak savannas have been severely degraded by logging, clearing for agriculture, fire suppression, invasion of exotic plants, and excessive livestock grazing. Savanna shares equal billing with tallgrass prairie as the most threatened plant community in the Midwest. As such, there is increasing interest in restoring these communities. Conservation criteria have not been developed for the post oak (Querces stellata) and blackjack oak (Querces marilandica) savanna of the Cross Timbers. Oak savanna was arguably an important component of the historical Cross Timbers region. Following settlement, overgrazing in conjunction with a decrease in fire frequency and/or intensity has increased the density of oak stands to the point where they resemble closed-canopy forests rather than savanna. This is a threat to the biodiversity of the Cross Timbers. Proactive land management practices are recommended for restoring savanna communities. Such efforts may require thinning-out areas of degraded oak savanna to help re-establish the herbaceous understory. Fire is recommended to restore ecological processes that limit woody plant encroachment and promote biodiversity. Further research should investigate the ecological dynamics and functions of oak savannas, as well as provide further guidelines for its conservation.
