Detecting prairie biodiversity with airborne remote sensing

This study assessed the application of airborne imaging spectroscopy to monitor α-diversity in restored grassland plots. The study site was located within the Central Platte River ecosystem, south of Wood River in Central Nebraska, USA, and consisted of two sets of plots (young and old). Exotic species had recently invaded the old plots, confounding the original study design, while the young plots did not have significant invasion by weeds, reflecting the original study design. We used spectral variation (i.e. spectral diversity, expressed as the coefficient of variation) as a proxy for α-diversity (expressed as species richness and Shannon index). Airborne data collected at two flight altitudes and two flight directions tested the validity of “spectral diversity-α-diversity” relationship at different sampling scales and flight directions. Our results showed a strong relationship between spectral diversity and α-diversity in young, non-invaded plots exhibiting strong differences in α-diversity. However, in the old, invaded plots, the spectral diversity-α-diversity relationship was non-significant. Factors likely contributing to this failure in the old plots included the spatial mismatch between airborne and field-based sampling, the convergence in diversity levels over time, and the unique reflectance signatures of the invasive species related to their different structural and phenological properties. Unlike previous airborne studies in manipulated experimental prairie plots, but similar to results in more natural settings, the strong spectral diversity-α-diversity relationship in the young plots remained even at the spatial resolution of 1 m, demonstrating the potential of airborne remote sensing to assess diversity patterns in prairie grasslands. These findings demonstrate the importance of experimental remote sensing in evaluating spectral diversity, and provide insight for the development of operational airborne methods to assess biodiversity

IT ORIGIN OF MOTHER1 s DaY - (May l2th/46) "April showers bring May Flowers" calls to mind Mother’s Day, the second Sunday in May, this year the twelfth. Miss Anna Jarvis, of Philadelphia, conceived the idea of Mother’s Day, when she was getting flowers to decor­ate Grafton Church for a memorial service to be held on May 9th, 1909 -- the second anniv­ersary of her mother's death. She wrote Kings, Governors, teachers and clergymen urging "although every day should be a day for honoring our mothers, let us set aside ono special day for the signifying of unfaltering love". Her letters brought wide response, and by 1914 President Wilson had proclaimed that the second Sunday in May would henceforth be ob­served throughout the United States as "Mother’ Day". Today forty-three nations throughout the world keep the day. Because her mother, Mrs. Anna Reeves Jarvis, had loved flowers, especially carnations, Miss Jarvis suggested that all wear white carnat­ions. With the passage of time "white for remembrance, and red for the living" has be­come the accepted rule, __ ___ ■*****.*..** ,___________________ _ _ MOTHER’S DaY CARDS............................................5^ aRTIIICaL Cb.KNaTIONS} red and white.. 150 each.

A Provincial wide campaign for the destruction of crows and magpies has heen launched by the Alberta Fish and Game Association, and the Magrath Rod & Gun Club is going to take an active part in this by the destruction of these predators. A bounty of five cents per pair for the feet of these birds is being off­ered by the provincial executive, and the local club from their own funds is paying 10 each for the eggs. No money will be paid out for hawk and owl feet or eggs during the spring campaign, as too many beneficial hawks are destroy­ed by hunters -who are unable to discern between good and destructive hawks. All hawks are not bad.
