Digby Wells Environmental ii Final Scoping Report Integrated Environmental Authorisations for the Proposed Expansion of the Nomalanga Estate, KwaZulu-Natal Province NOM5486 EXECUTIVE SUMMARY Introduction Nomalanga Property Holdings (Pty) Ltd intends to expand the agro processing and agricultural development and operations within the Nomalanga Estate located 15 kilometres (km) West of Greytown, along the D222 road, within the Umvoti Rural District, Kwazulu-Natal (KZN) Province. There is currently a shade house covering 5 hectares (ha) under fertigation/drip irrigation, a 200m2 pack house unit with cooling facilities and an afforested area (approximately 273 ha in size). The current water source is a single borehole as the main dam is still recovering from the drought. Nomalanga Estate further comprises a 2 648 ha Nature Reserve, the Nomalanga Nature Reserve, which was gazetted on 19 November 2013 in terms of the National Environmental Management: Protected Areas Act, 2003 (Act No. 57 of 2003) and declared a Stewardship site by Ezemvelo KZN Wildlife. Within the Estate, 300 ha have been earmarked for intense agricultural production. Facilities intended for waste-water treatment, food processing and staff accommodation also fall within the scope of the Project.

Environmental risks associated with such a project are also identified and mitigation measures proposed. The completion of an EIA is a regulatory requirement in terms of the provisions of the National Environmental Management Act, 1998 (Act No. 107 of 1998) (NEMA) and the EIA process which is regulated in accordance with the EIA Regulations, 20141. The overarching purpose of the EIA process is to determine, assess and evaluate the environmental and social consequences (positive and negative) of a proposed development, activity or project. This Scoping Report forms part of the EIA process and aims to identify those biophysical and socio-economic issues or concerns that require investigation as well as determine feasible alternatives. This information is then used to determine the scope of work for the impact assessment phase of the EIA process. During the scoping phase, people interested and/or affected by the project are informed of the project as well as provided the opportunity to raise issues and concerns they may have. The objectives of the scoping report are, therefore, to: ■ Describe the Project and the associated activities; ■ Provide a summary of the Baseline Environment; ■ Predict potential positive and negative impacts as a result of the Project and its activities, and identify potential measures to minimise negative impacts and enhance positive impacts; ■ Provide a proposed Plan of Study for the EIA Phase of the process; and ■ Share the Project information with Interested and Affected Parties (I&APs) and to record the issues and comments raised by all stakeholders. Summary of the Baseline Environment Nomalanga Estate falls within the Umvoti Local Municipality (ULM) and Umzinyathi District Municipality (UDM). The proposed expansion areas comprises of areas with gentle slopes and higher-lying areas with steeper slopes. The Project area is characterised by good soils and moderate topography which makes the area highly viable for agricultural activities. The Project area is located predominantly within the Sub-Escarpment Grassland Bioregion of the Temperate Grassland Biome (TGB) and within the Sub-Escarpment Savanna Bioregion of the Savanna Biome. There are four vegetation types found within Nomalanga Estate, namely the KZN Highland Thornveld, Midlands Mistbelt Grassland, Thukela Valley Bushveld and Temperate Alluvial Vegetation. The KZN Highland Thornveld and Temperate 1 Environmental Impact Assessment (EIA) Regulations, 2014 (GN R 982 of 4 December 2014 as amended by GN R326 of 7 April 2017) (EIA Regulations, 2014), as amended promulgated under the National Environmental Management Act, 1998 (Act No. 107 of 1998) (NEMA) Digby Wells Environmental iv Final Scoping Report Integrated Environmental Authorisations for the Proposed Expansion of the Nomalanga Estate, KwaZulu-Natal Province NOM5486 Alluvial Vegetation are listed as “least threatened” ecosystems, while the Midlands Mistbelt Grassland is listed as “Endangered”. Thukela Valley Bushveld is statutorily conserved (less than 200 ha). According to the KZN Biodiversity Sector Plan, a large portion of the Project area is characterised as “Critical Biodiversity Area – Irreplaceable”. These areas are considered critical for meeting biodiversity targets and are required to ensure the persistence of viable populations of species including the functionality of ecosystems. Nomalanga Estate comprises a 2 748 ha nature reserve, the Nomalanga Nature Reserve, and is in close proximity to two nature reserves, namely the Blinkwater Nature Reserve and Umvoti Vlei Nature Reserve. Nomalanga Estate falls within the Pongola-Mtamvuna Water Management Area (WMA4) consisting of two separate quaternary catchments (i.e. catchments V20G and V20H) and three Sub-Quaternary Reaches (i.e. Mbalane, Mhlopheni and Nyambathi). The wetland types that dominate the landscape are seeps, flats and valley floor wetlands, which range from high to low importance in terms of conservation significance. The heritage resources identified within the Project area include burial grounds and graves and potential historical buildings, which are expressions from the Southern African Stone Age, Farming Community and Historical Periods. The current land uses associated with the Project area and surrounds includes farms, forests, agriculture and residential areas. Approach and Methodology for the Public Participation Process A Public Participation Process has been initiated, which is central to the investigation of environmental and social impacts, as it is important that stakeholders who are affected by the Project are given an opportunity to identify concerns to ensure that local knowledge, needs and values are understood and taken into consideration as part of the EIA process. The Draft Scoping Report was made available for public comment for a period of 30 days and all comments or concerns raised will be recorded and responded to in the Comments and Responses Report (CRR). The 30 day comment period was from 12 November 2018 until 11 December 2018, initially. This period was thereafter extended to the 16 January 2019. The following activities were undertaken as part of the Scoping Phase: ■ A Background Information Document (BID) was distributed via e-mail on 12 November 2018; ■ Newspaper advertisement was placed on 14 November 2018 in the Greytown Gazette Newspaper; ■ An announcement letter including a registration form was distributed

E, Riverside, CA 92501, USA dCollege of Life Sciences, Peking Univerisity, Beijing, China Received 5 May 2005; received in revised form 29 November 2005; accepted 29 November 2005 Abstract Glassy-winged sharpshooter, Homalodisca coagulata (Say), is an efficient vector of Xylella fastidiosa (Xf), the causal bacterium of Pierce’s disease, and leaf scorch in almond and oleander. Acquisition and inoculation of Xf occur sometime during the process of stylet penetration into the plant. That process is most rigorously studied via electrical penetration graph (EPG) monitoring of insect feeding. This study provides part of the crucial biological meanings that define the waveforms of each new insect species recorded by EPG. By synchronizing AC EPG waveforms with high-magnification video of H. coagulata stylet penetration in artifical diet, we correlated stylet activities with three previously described EPG pathway waveforms, A1, B1 and B2, as well as one ingestion waveform, C. Waveform A1 occured at the beginning of stylet penetration. This waveform was correlated with salivary sheath trunk formation, repetitive stylet movements involving retraction of both maxillary stylets and one mandibular stylet, extension of the stylet fascicle, and the fluttering-like movements of the maxillary stylet tips.

  • Insect Classification Standards 2020
    RECOMMENDED INSECT CLASSIFICATION FOR UGA ENTOMOLOGY CLASSES (2020) In an effort to standardize the hexapod classification systems being taught to our students by our faculty in multiple courses across three UGA campuses, I recommend that the Entomology Department adopts the basic system presented in the following textbook: Triplehorn, C.A. and N.F. Johnson. 2005. Borror and DeLong’s Introduction to the Study of Insects. 7th ed. Thomson Brooks/Cole, Belmont CA, 864 pp. This book was chosen for a variety of reasons. It is widely used in the U.S. as the textbook for Insect Taxonomy classes, including our class at UGA. It focuses on North American taxa. The authors were cautious, presenting changes only after they have been widely accepted by the taxonomic community. Below is an annotated summary of the T&J (2005) classification. Some of the more familiar taxa above the ordinal level are given in caps. Some of the more important and familiar suborders and families are indented and listed beneath each order. Note that this is neither an exhaustive nor representative list of suborders and families. It was provided simply to clarify which taxa are impacted by some of more important classification changes. Please consult T&J (2005) for information about taxa that are not listed below. Unfortunately, T&J (2005) is now badly outdated with respect to some significant classification changes. Therefore, in the classification standard provided below, some well corroborated and broadly accepted updates have been made to their classification scheme. Feel free to contact me if you have any questions about this classification.

  • The Water Bugs (Hemiptera; Heteroptera) from the Western Thong Pha Phum Research Project Area, Kanchanaburi Province, Thailand
    รายงานการวิจัยในโครงการ 38-51 ชุดโครงการทองผาภูมิตะวันตก The Water Bugs (Hemiptera; Heteroptera) from the Western Thong Pha Phum Research Project Area, Kanchanaburi Province, Thailand Chariya Lekprayoon*, Marut Fuangarworn and Ezra Mongkolchaichana Chulalongkorn University, Bangkok *[email protected] Abstracts: Water bugs belong to the order Hemiptera, suborder Heteroptera which contains two kinds of members; semiaquatic (Gerromorpha), and true water bugs (Nepomorpha). They play a major role as biological control agents, and ecologically as food for higher trophic levels (birds and fish). This study is aimed at ascertaining the basic biodiversity and distribution, as well as biological and ecological based data, of water bugs in Thailand and to this aim this part the research was conducted at 4 locations of lotic habitats during May 2002 to April 2003 and at 4 wetland locations during May 2005 to June 2006, in the western Thong Pha Phum research project area. Data on the physical factors of each location were recorded at the time of collection of water bugs. Fifty-six species, from 49 genera and 14 families, were identified but this is an underestimate of the true biodiversity with and more than 16 different morphospecies likely to represent but true different species still in the process of identification. Timasius chesadai Chen, Nieser and Lekprayoon, 2006 (Hebridae) was found and described as a new species and the first record from Thailand. To aid future researchers, a key to families of Heteroptera within the Thong Pha Phum area of Thailand was prepared and is presented along with summary biological and ecological information at the family level. This report on species diversity of water bugs suggests that at least 72 species are expected to have been found from the west Thong Pha Phum area, a small part of Thailand.

BENJAMIN Rancho Santa Ana Botanic Garden Claremont, California INTRODUCTION The Hemiptera, or true bugs, a large and diverse assemblage of insects, are characterized by ( 1) mouth-parts articulated into an often elongate tubular beak adapted for feeding on plants or animals by piercing and sucking, ( 2) gradual metamorphosis, and ( 3) overlapping front wings having a hardened basal part, the corium, and a thin, transparent apex, the membrane. The order commonly is divided into two suborders, the Homoptera and the Heteroptera ( Brues, Melander & Carpenter, 1954; Ross, 1956). At present no member of the Homoptera (which includes such well-known bugs as the cicadas, tree hoppers, plant lice, etc.) is known to be parasitized by Laboulbeniales. These fungi occur on insects classi­ fied in the Heteroptera, but only 26 species have been described. Entomologists subdivide the Heteroptera into two major groups based, in part, on the length of the antennae. These are the Cryptocerata (short-horned bugs) in which the antennae are short and are concealed beneath the head and the Gymnocerata (long-horned bugs) in which the antennae typically are longer than the head and are exposed.
