CEPF SMALL GRANT FINAL PROJECT COMPLETION REPORT I. BASIC DATA Organization Legal Name: Nature’s Valley Trust Project Title (as stated in the grant agreement): Nature’s Valley Water Opal Wetland Rehabilitation Project Implementation Partners for This Project: Project Dates (as stated in the grant agreement): November 1, 2006 – July 31, 2007 Date of Report (month/year): September 2007 II. OPENING REMARKS Provide any opening remarks that may assist in the review of this report. We have been extremely disappointed at our local Municipality’s response to this project and hope, in time, that through further discussion, we will be able to create more understanding of the importance of this proposed project and its benefits to the local environment and its communities. III. NARRATIVE QUESTIONS 1. What was the initial objective of this project? The objectives of this project were two-fold: a. To rehabilitate an existing small wetland site in order to assist in filtering storm water from a storm-water canal which feeds into the Groot River estuary; b. To establish the site as an outdoor classroom for school groups and visitors to Nature’s Valley. 2. Did the objectives of your project change during implementation? If so, please explain why and how. Unfortunately, due to a decision made by our local Municipality, we have been unable to create the proposed wetland site. Despite this, the objectives of the project remain unchanged and it is hoped that we will, at a future date, be able to fulfill these objectives. 3. How was your project successful in achieving the expected objectives? An educational resource and information board has been developed pertaining to wetlands in the area (see appendices 4 and 5). -

LATE SUMMER EDITION: JANUARY / AFRICAN FEBRUARY 2018 - 1 BUTTERFLY THE LEPIDOPTERISTS’ SOCIETY OF AFRICA NEWS LATEST NEWS Welcome to the first newsletter of 2018! I trust you all have returned safely from your December break (assuming you had one!) and are getting into the swing of 2018? With few exceptions, 2017 was a very poor year butterfly-wise, at least in South Africa. The drought continues to have a very negative impact on our hobby, but here’s hoping that 2018 will be better! Braving the Great Karoo and Noorsveld (Mark Williams) In the first week of November 2017 Jeremy Dobson and I headed off south from Egoli, at the crack of dawn, for the ‘Harde Karoo’. (Is there a ‘Soft Karoo’?) We had a very flexible plan for the six-day trip, not even having booked any overnight accommodation. We figured that finding a place to commune with Uncle Morpheus every night would not be a problem because all the kids were at school. As it turned out we did not have to spend a night trying to kip in the Pajero – my snoring would have driven Jeremy nuts ... Friday 3 November The main purpose of the trip was to survey two quadrants for the Karoo BioGaps Project. One of these was on the farm Lushof, 10 km west of Loxton, and the other was Taaiboschkloof, about 50 km south-east of Loxton. The 1 000 km drive, via Kimberley, to Loxton was accompanied by hot and windy weather. The temperature hit 38 degrees and was 33 when the sun hit the horizon at 6 pm. -

Butterfly Conservation in Oak Savanna: Site Characterization, Nectar Resources, and the Effects of Management
BUTTERFLY CONSERVATION IN OAK SAVANNA: SITE CHARACTERIZATION, NECTAR RESOURCES, AND THE EFFECTS OF MANAGEMENT Lauren E. Yarrish A Thesis Submitted to the Graduate College of Bowling Green State University in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE May 2011 Committee: Karen V. Root, Advisor Helen J. Michaels Jeffrey G. Miner ii ABSTRACT Karen V. Root, Advisor Oak savanna is a globally imperiled plant community characterized by scattered oak trees and an herbaceous ground layer. The Oak Openings Region in northwest Ohio was once dominated by oak savanna however, since European settlement the amount of oak savanna has been significantly reduced. Despite the large reduction in area, what remains continues to support high levels of biodiversity including several rare butterfly species such as the federally endangered Karner blue butterfly (Lycaeides melissa samuelis). To improve butterfly conservation efforts, this study sought to characterize and compare oak savanna sites, determine how butterflies utilize nectar resources, and assess the effects of land management practices in the Oak Openings Region. We conducted vegetation surveys at four oak savanna sites. Transects were established at each site and a quadrat frame was placed every 10 m along the transects. At each quadrat we recorded several factors known to be important to butterflies, such as flowering plant density, canopy cover, vegetation height etc. We also conducted opportunistic behavioral observations of butterflies, recording behavior at 10 minute intervals. Lastly, we obtained land management records from local agencies. Sites varied greatly with respect to the measured factors. Flowering plant densities were low compared to a previous study used to evaluate potential reintroduction sites for the Karner blue butterfly in northwest Ohio. -
Some Ecological Factors Influencing the Breeding Success of the Brenton Blue Butterfly, Orachrysops Niobe (Trimen) (Lepidoptera: Lycaenidae)
Edge.qxd 2005/12/09 10:02 Page 19 Some ecological factors influencing the breeding success of the Brenton Blue butterfly, Orachrysops niobe (Trimen) (Lepidoptera: Lycaenidae) D.A. EDGE Edge, D.A. 2002. Some ecological factors influencing the breeding success of the Bren- ton Blue butterfly, Orachrysops niobe (Trimen) (Lepidoptera: Lycaenidae). Koedoe 45(2): 19–34. Pretoria. ISSN 0075-6458. The Brenton Blue butterfly, Orachrysops niobe (Trimen, 1862) (Lepidoptera: Lycaenidae), is endemic to the southern Cape and is currently listed as Endangered. This study looks at some of the key ecological factors influencing the breeding success of the species—host plant abundance and condition, nectar sources, climate/ microclimate, and vegetation management techniques. The adult butterfly population was monitored over an entire breeding season; host plants were identified and individually monitored; and egg counts were done. This enabled the effects of a number of different manage- ment techniques to be evaluated (burning, cutting, physical removal of invasive ele- ments, and combinations thereof). A fivefold increase in the population of O. niobe was observed over the breeding season. This increase was positively correlated to a similar increase in host plant abundance in the areas where cutting and physical removal of invasive elements was practiced. Burning, by contrast, appeared to have a negative impact on host plant and butterfly abundance over the same period. Impacts of other fac- tors such as climate, nectar sources and the natural strength of the second brood are dis- cussed. A hypothesis, of megaherbivore activity as the principal historical disturbance mechanism promoting locally favourable conditions for O. niobe to establish and main- tain colonies, is proposed. -

Brenton Blue News – November 2017
BRENTON BLUE NEWS – NOVEMBER 2017 Welcome all friends and neighbours of the Brenton Blue butterfly (Orachrysops niobe) to your latest newsletter! You can obtain more detailed information about niobe (see note below) on the Brenton Blue Trust website www.brentonbluetrust.co.za. Research progress following the 7th June 2017 fire Introduction The Knysna fire of 7th June 2017 was probably the most intense and widespread fire in the southern Cape since the famous 1869 fire. It swept from west to east along the Brenton peninsula, propelled by a gale force westerly wind (gusting to over 100km/h) burning almost everything in its path until it eventually reached the Brenton Blue Butterfly Reserve (BBBR), and both the original reserve (1.6 ha) and the expansion sections (13.5 ha) were severely burnt. The impact of such a fire on a butterfly such as niobe is unknown. Consequently the aftermath of this fire represents an opportunity to do some extremely important research into the potential recovery of this species and its habitat. Aims and objectives of the research The overall aim is to monitor the post-fire recovery of the ecosystem at the BBBR, mainly focusing on the status of the critical ecological factors needed for niobe to survive (host plants, host ants, candlewood trees, nectar plants, vegetation communities, microclimate) and compare that with pre- fire ecosystem as recorded by Edge in 2005. The research objectives therefore include: 1. Recording the recovery of the vegetation communities and compare with the pre-fire data. 2. Quantify the regrowth of niobe’s host plant I. -

We studied egg-laying patterns and landscape occupancy of two sympatric lycaenidae butterflies inhabiting xeric grasslands, vulnerable Polyommatus thersites and critically endangered Polyommatus [Agrodiaetus] damon, both developing on sainfoin, Onobrychis spp. Females of bivoltine P. thersites oviposit on host plant leaves at a relatively low height (≈20 cm), in both spring (May–June) and summer (July–August) generations. Females of univoltine P. damon (July–September) oviposit to senescing inflorescences, in significantly higher heights (>30 cm), and the species is hence vulnerable to summer mowing or grazing. On a landscape scale, both species tended to occur at sites with diverse sward management, including temporarily unmanaged patches. In addition, P. damon occurred only in the proximity of other
