<I>In situ </I>conservation is considered as conservation of wild biota in the natural habitat (locality). The authors extend the term to cultivated fruit species naturalised in the landscape, such as occasional spontaneous seedlings, and planted material such as old solitary trees among fields, old groves, avenues (country lanes), wind-breaks, and abandoned remnants of orchards. <I>In situ </I>conservation is also used to mark unique materials during collecting expeditions, before they will be taken as <I>ex situ </I>or proclaimed as permanent <I>in situ</I>. Important landraces found within 12 regions of the Czech Republic were registered, evaluated, and <I>in situ </I>localised by Global Positioning System (GPS). The following accessions were marked for in-situ conservation: apple (401), sweet cherry (263), pear (91), plum (42), sour cherry (27), and berry fruits (18).

Abstract Central Kalimantan Province with total area of 15.380.000 ha or about 7.93 % of Indonesian areas consists of coastal regions and forest areas has potential biodiversity such as Orchidaceae. This region has various type of lands involving peat lands, swamplands with acid sulphate soils and up lands. The existence of orchid in Central Kalimantan’s forest can be found scattered in forest areas with high diversity life, form and uses. The methodology used include exploration and collection and they were conducted at six districts, i.e. East Barito, South Barito, North Barito, East Kotawaringin and Murung Raya, starting from March 2016 until December 2018. The objective of this study was as follows: (1). The exploration process, (2). The ex-situ and in-situ conservation, (3). The characterization process, (4). The documentation process. The results of these activities shown that there are several ex situ collection of 8 accessions of medicinal plants that can be used as a source of material for genetic improvement. The orchid plant’s conservation can be conducted through in-situ and or ex-situ. In-situ conservation can be conducted through managing forest areas as the natural habitat of the material for genetic improvement, while for ex-situ conservation, it can be managed outside of the native habitats. Appropriate utilization and research activities are important in conservation of the material for genetic improvement in Central Kalimantan

The Status

This study presents the status of ex situ and in situ conservation for the crop wild relatives of rice, potato, sweet potato, and finger millet in Brazil, and the subsequent germplasm collection expeditions. This research is part of a global initiative entitled “Adapting Agriculture to Climate Change: Collecting, Protecting, and Preparing Crop Wild Relatives” supported by the Global Crop Diversity Trust. Species of the primary, secondary, and tertiary gene pools with occurrences reported in Brazil were included: Oryza alta Swallen, O. grandiglumis (Döll) Prod., O. latifolia Desv., O. glumaepatula Steud., Eleusine tristachya (Lam.) Lam., E. indica (L.) Gaertn., Solanum commersonii Dunal, S. chacoense Bitter, Ipomoea grandifolia (Dammer) O’Donell, I. ramosissima (Poir.) Choisy, I. tiliacea (Willd.) Choisy, I. triloba L., and I. cynanchifolia Meisn. The status of the ex situ and in situ conservation of each taxon was assessed using the gap analysis methodology, and the results were used to plan 16 germplasm collection expeditions. Seeds of the collected material were evaluated for viability, and the protocols for seed germination and cryopreservation were tested. The final conservation score, resulting from the gap analysis and including the average of the ex situ and in situ scores, resulted in a classification of medium priority of conservation for all the species, with the exception of I. grandifolia (high priority). The total accessions collected (174) almost doubled the total accessions of these crop wild relatives incorporated in Embrapa’s ex situ conservation system prior to 2015. In addition, accessions for practically absent species were collected for the ex situ conservation system, such as Ipomoea species, Eleusine indica, and Solanum chacoense. The methods used for dormancy breaking and low temperature conservation for the Oryza, Eleusine, and Ipomoea species were promising for the incorporation of accessions in the respective gene banks. The results show the importance of efforts to collect and conserve ex situ crop wild relatives in Brazil based on previous gap analysis. The complementarity with the in situ strategy also appears to be very promising in the country.

AbstractConservation programmes are always limited by available resources. Careful planning is therefore required to increase the efficiency of conservation and gap analysis can be used for this purpose. This method was used to assess the representativeness of current ex situ and in situ conservation actions of 234 priority crop wild relatives (CWR) in Indonesia. This analysis also included species distribution modelling, the creation of an ecogeographical land characterization map, and a complementarity analysis to identify priorities area for in situ conservation and for further collecting of ex situ conservation programmes. The results show that both current ex situ and in situ conservation actions are insufficient. Sixty-six percent of priority CWRs have no recorded ex situ collections. Eighty CWRs with ex situ collections are still under-represented in the national genebanks and 65 CWRs have no presence records within the existing protected area network although 60 are predicted to exist in several protected areas according to their potential distribution models. The complementarity analysis shows that a minimum of 61 complementary grid areas (complementary based on grid cells) are required to conserve all priority taxa and 40 complementary protected areas (complementary based on existing protected areas) are required to conserve those with known populations within the existing in situ protected area network. The top ten of complementary protected areas are proposed as the initial areas for the development of CWR genetic reserves network in Indonesia. It is recommended to enhanced coordination between ex situ and in situ conservation stakeholders for sustaining the long term conservation of CWR in Indonesia. Implementation of the research recommendations will provide for the first time an effective conservation planning of Indonesia’s CWR diversity and will significantly enhance the country’s food and nutritional security.

This study was conducted from March 2017 to August 2018, to enumerate the quantitative attributes and current status of medicinal plants of Sheen Ghar Valley, District Dir Lower, Pakistan. A total of 51 species were documented for their medicinal uses. These plants belonged to 31 families. Results of this study revealed that leaves were the frequently used part (50%), followed by whole plants (only 30%) in curing different ailments. Many plants were found to be having multiple uses. Based on family importance value (FIV), Lamiaceae was the leading plant family (126.30) followed by Violaceae (55.81), while highest relative frequency of citation (RFC) was noted for Viola canescens (0.558) followed by Olea europaea (0.523). Conservation study revealed that 24 species (47%) were vulnerable, 22 species (43%) were rare and 4 species (8%) were noted as infrequent. Following IUCN standards for conservation, one species i.e. Hypericum perforatum was declared dominant. This study recommends immediate ex-situ and in-situ conservation programme for protecting the plant wealth of the locality.

Methylation Patterns

Epigenetic variation, and particularly DNA methylation, is involved in plasticity and responses to changes in the environment. Conservation biology studies have focused on the measurement of this variation to establish demographic parameters, diversity levels and population structure to design the appropriate conservation strategies. However, in ex situ conservation approaches, the main objective is to guarantee the characteristics of the conserved material (phenotype and epi-genetic). We review the use of the Methylation Sensitive Amplified Polymorphism (MSAP) technique to detect changes in the DNA methylation patterns of plant material conserved by the main ex situ plant conservation methods: seed banks, in vitro slow growth and cryopreservation. Comparison of DNA methylation patterns before and after conservation is a useful tool to check the fidelity of the regenerated plants, and, at the same time, may be related with other genetic variations that might appear during the conservation process (i.e., somaclonal variation). Analyses of MSAP profiles can be useful in the management of ex situ plant conservation but differs in the approach used in the in situ conservation. Likewise, an easy-to-use methodology is necessary for a rapid interpretation of data, in order to be readily implemented by conservation managers.

Research Areas

Two tree species native to North America, American chestnut (Castanea dentata (Marsh.) Borkh.) and butternut (Juglans cinerea L.), which have experienced rapid declines in their populations due to similar stressors (disease and changes in land use), are used as examples of how these species would benefit from ex situ conservation efforts. Current and past ex situ and in situ conservation efforts for these species are discussed and the focus of this review is on two key research areas: 1) what needs to be preserved (genetic information) and 2) how to preserve these trees or germplasm. Key words: butternut, American chestnut, Cryphonectria parasitica, Sirococcus clavigignenti-juglandacearum, ex situ conservation
