The 54th congress of the GSSA was recently held in Upington. This was a great success and delegates enjoyed the diversity of the Northern Cape. This year the congress started differently where tours were held at the beginning of the event and ran concurrently with the Research Skills Workshop: An introductory course to the statistical programme, R. Despite the windy weather, field trips were enjoyed by many. A brief summary and some photographs are included in this Grassroots. Congress officially opened on Monday evening and attendees enjoyed the variety of presentations, posters, discussion sessions and network opportunities. This issue of Grassroots contains some of the highlights of the event. In this issue, Justin du Toit presents us with a neat solution to what the singular word is for cattle. Something useful for next time we need to refer to a single bovine animal! The Grassroots photo competition is going well and, in this issue, we congratulate our overall winner, Sigrun Ammann, on her photo titled “Lush kikuyu/ryegrass pasture at the foot of the Outeniqua mountains”. Well done Sigrun! Please continue to support our competition and carry on submitting your interesting photos. Good news is that we have had confirmation from the South African Council for Natural Scientific Professions (SACNASP) that authors of feature articles can now claim a single CPD point for each article submitted, so please keep us updated with your feature articles. Until next time, happy reading!

Welcome to Issue 2 of Grassroots for 2019! In this full edition, we start with a fea¬ture article by Everson et al., where we are introduced to some new research on bamboo in South Africa. Bamboo has the potential to reduce deforestation of South Africa’s natural forest by providing a source of fuelwood and building material. The water-use of this plant is not well understood under South African conditions and this DWS and WRC funded study aims to understand the effects of different bamboo species on water-use. In our second feature article, Charné Viljoen presents recent research on nitrogen application rates on planted pastures. This study illustrated that, under current management practices, there is a major pool of leachable nitrate and suggests lower application rates for kikuyu pastures and kikuyu pastures over-sown with ryegrass compared to the conventional guidelines. Lower nitrogen rates will allow volunteer legumes to fix nitrogen as well as allow the pasture to use the mineralised nitrogen. Finally, Costas Zachariades, from the PHP-ARC announces the introduction of the Tradescantia tip beetle into South Africa. This beetle has been bred as a biocontrol for Tradescantia fluminensis (Wandering Jew), an invasive alien plant that is affecting the recruitment of forest trees in the higher rainfall areas of SA. Our news articles, as usual, cover a variety of topics, ranging from the use of technology in conservation, long-term monitoring of vegetation and floating solar panels to invasive alien plants and conservationists who share similar views. In the previous issue, we introduced a photographic competition to get an idea of the interesting experiences and opportunities our readers have had in the field. Thank you to all who have supported this idea and all those who continue to support. The quality of your photos made judging a challenge. The winner for this issue’s cover photo is Greg Martindale with his great photo of research in action – Congratulations! We have also published the runners-up from each category in this issue for you to enjoy. Please keep submitting your pictures: your photo could be on the cover of the next issue of Grassroots. A reminder that our GSSA Congress is now just around the corner. Please remember to register as soon as possible! This year’s congress will be held in Upington from 1 - 4 July and we look forward to seeing you there. More information on the congress is found in this issue. Until next time, happy reading!

March 2019

This issue contains a variety of recent news articles, hopefully there’s some¬thing in here for everyone! These articles range from invasive species, soil fertility management and Lablab purpureus – a species used as a dry-season feed in Kenya to sustainable livestock production and key perfor-mance indicators for dairy farmers. We also would like to see what inter¬esting fieldwork our readers are up to and so we have started off the new year with a photo¬graphic competi¬tion. Here we invite you to submit any photos related to rangeland ecology and pasture man¬agement into our competition and your photo may be on the next cover of Grassroots. Any interesting photos taken while doing fieldwork are also encouraged – and will be put into our next issue! We would also like to hear of any achieve¬ments among our members – please let us know if you have recently completed your Masters or Doctorate or received any special awards. Finally, a reminder of the 54th GSSA Congress coming up later this year in Upington. Registration is now open, and abstracts can be submitted. It will be great to see you all there! Happy reading!

December 2018

Welcome to the fourth and final edition of Grassroots for 2018. As usual, this publication con¬tains a variety of news articles and a feature article by Chloe Maclaren, one of our members who is currently com¬pleting her PhD. Chloe introduces us to a method of integrating sheep into crop rotations – this aids in managing weeds which can save money and pro¬tect the environment. Some of the interesting local news is¬sues covered in this edition include those from Paul Gordijn and Tim O’Connor (SAEON) who have been looking at vegetation change in the Cathedral Peak grasslands and the response to different fire treatments. Wendy Collinson (EWT) introduces the new Brake4Wildlife project to try to reduce roadkill in protected ar¬eas, while Erik Verreyne explains the process of mapping the vegetation of Orapa Game Park. More on the global news front, we have a sum¬mary of Cromsigt et al’s paper on the use of large mammals for a better cli¬mate and Jack Durrell has created an awareness on the potential of Africa’s rangelands through his recently pub¬lished article. As the year draws to an end, the editorial team would like to thank all who have contributed to Grassroots throughout the year and would like to encourage all readers to send articles (both news and feature) to Grassroots in the new year. Finally, we wish all our readers safe travels, a happy festive season and all the best for a great new year. Happy reading!

Memories through photographs, a summary of the 53rd conference, the outgoing presidential address. Two feature articles; one about being resourceful with some field equipment and the second looked into the challenges and opportunities for forage feed systems in East Africa. Articles also include Indalo Game Reserves Protected Environment, a 68 075 ha conservation area in the Eastern Cape and SAEON’s Lower Orange River Riparian Project, news on bush encroachment and the impact of shothole borer on our trees. Included is an “upcoming events page”. Please, if you are organising or know of any event of interest, and would like the Grassroots community to hear about it, contact us with the details and we will include it in the next issue.
