New Plantings in the Arboretum the YEAR in REVIEW
Four new have been Four new Yoshino cherry trees have Yoshinobeen planted along planted Azalea Way. cherry trees along Azalea New Plantings in the Arboretum THE YEAR IN REVIEW T EX T B Y R AY L A R SON P HO T OS B Y N IA ll D UNNE n the five years that I have been curator, 2018 was the most active in terms of new plantings in the Arboretum. A majority of these centered around the new Arboretum Loop Trail and adjacent areas, many of which were enhanced, rehabilitated and Iaugmented. We also made improvements to a few other collection and garden areas with individual and smaller plantings. Following is a summary of some of the more noticeable new plantings you might encounter during your next visit. Winter 2019 v 3 Arboretum Entrance Perhaps the most obvious major planting occurred in March, just north of the Graham Visitors Center, with the creation of a new, large bed at the southeast corner of the intersection of Arboretum Drive and Foster Island Road. This intersection changed a lot as part of the Loop Trail construction—with the addition of new curbs and crosswalks—and we wanted to create a fitting entrance to the Arboretum at its north end. The new planting was also intended to alleviate some of the soil compaction and social trails that had developed on the east side of Arboretum Drive during trail construction. What’s more, we wanted to encourage pedes- trians to use the new gravel trail on the west side of the Drive to connect from the lower parking lots to the Visitors Center—rather than walk in the road. -

Then his Natural History of the Ducks in 1926, he Mayr (1931a) was able to examine a dead noted that Salvadori’s Duck Salvadorina specimen and found that the sternum and (Anas) waigiuensis was ‘the last to be brought trachea of the male were, although smaller, to light and perhaps the most interesting of the similar to those of the Mallard Anas platy peculiar anatine birds of the world’. It was still rhynchos. As a result, Salvadori’s Duck was practically unknown in 1926; the first moved to the genus A nas. However, as recorded wild nest was not seen until 1959 (H.

Disaggregation of Bird Families Listed on Cms Appendix Ii
Convention on the Conservation of Migratory Species of Wild Animals 2nd Meeting of the Sessional Committee of the CMS Scientific Council (ScC-SC2) Bonn, Germany, 10 – 14 July 2017 UNEP/CMS/ScC-SC2/Inf.3 DISAGGREGATION OF BIRD FAMILIES LISTED ON CMS APPENDIX II (Prepared by the Appointed Councillors for Birds) Summary: The first meeting of the Sessional Committee of the Scientific Council identified the adoption of a new standard reference for avian taxonomy as an opportunity to disaggregate the higher-level taxa listed on Appendix II and to identify those that are considered to be migratory species and that have an unfavourable conservation status. The current paper presents an initial analysis of the higher-level disaggregation using the Handbook of the Birds of the World/BirdLife International Illustrated Checklist of the Birds of the World Volumes 1 and 2 taxonomy, and identifies the challenges in completing the analysis to identify all of the migratory species and the corresponding Range States. The document has been prepared by the COP Appointed Scientific Councilors for Birds. This is a supplementary paper to COP document UNEP/CMS/COP12/Doc.25.3 on Taxonomy and Nomenclature UNEP/CMS/ScC-Sc2/Inf.3 DISAGGREGATION OF BIRD FAMILIES LISTED ON CMS APPENDIX II 1. Through Resolution 11.19, the Conference of Parties adopted as the standard reference for bird taxonomy and nomenclature for Non-Passerine species the Handbook of the Birds of the World/BirdLife International Illustrated Checklist of the Birds of the World, Volume 1: Non-Passerines, by Josep del Hoyo and Nigel J. Collar (2014); 2. -

Potpourri Planting” – Be Brave!! Some Aspects of Tree Planting & Aftercare
Avoid weak “potpourri planting” – be brave!! Some Aspects of Tree Planting & Aftercare Poor stock, poor staking, no watering, no mulching “Cynical Tokenism” (Alan Simson) Plonking by Plonkers Poor Positioning? Right tree Right place? Clay soil - Smearing – Gypsum may help [Calcium sulphate] Amazing success planting in rubble blinded with soil Good aeration + great gaseous exchange O2 in Co2 out Stockholm – Structural soil + crushed rock + nutrients + Biochar + aeration 1. Selected surfacing 2. Upper sub base minimum 300mm 3. Root directors 4. Aeration and irrigation inlet cover 5. Rootball 6. Treebunker posts 7. Soil infill 8. Irrigation pipe 9. Geotextile 10. Lower sub base usually 100mm deep. Nursery Stock Quality A good bare-rooted tree Less good - reject Pot-bound root systems are OK – but you must damage them! Planting pits – square? As wide as possible and only as deep as the root system. Mound Planting On heavy clay or shallow soils. But is this proper mound planting? Backfill and Soil Ameliorants Snake Oil?: Worth considering?: • Mycorrhizal inoculants • Organic matter [10% max] and/or grit • Seaweed extract • Sugar • Planting compost? • Probiotics • Auxins • Rigel-G • Hydro gels • Biochar • Bark & wood chips [mulch] ‘Garden’ Placenta Aftercare Weed control Glyphosate?

FARMERI, MARIA C. FARMER2 and RAINER BERGER3 ABSTRACT. Extensive eruptions of alkalic basalt from low-elevation fissures and vents on the southern flank of the dormant volcano, Cerro Evermann, accompanied the most recent phase of volcanic activity on Socorro Island, and created 14C the Lomas Coloradas, a broad, gently sloping terrain comprising the southern part of the island. We obtained ages of 4690 ± 270 BP (5000-5700 cal BP) and 5040 ± 460 BP (5300-6300 cal BP) from lacustrine deposits that occur within volcanic sequences of the lower Lomas Coloradas. Apparently, the sediments accumulated within a topographic depression between two scoria cones shortly after they formed. The lacustrine environment was destroyed when the cones were breached by headward erosion of adjacent stream drainages. -
