Pinus durangensis - Durango pine, Pino blanco, Pino real (Spanish)
Conservation Status Red List Category & Criteria: Near Threatened The large extent of occurrence and the area of occupancy based on comprehensive locality sampling and a grid width of 10 km because this is a forest forming species, both place it outside a threatened category. However, exploitation has reduced formerly “extensive pure forests in Durango and southern Chihuahua… to only scattered, open stands over most of its range” (Perry 1991). It is therefore listed as Near Threatened as it nearly meets the criteria A2cd; B2ab(ii,iii,v) for listing as threatened. Although this decline has not ceased there is insufficient data to allocate one of the threatened categories. The change in status since the previous assessment of Least Concern, can therefore be seen as a genuine recent change. Populations have been substantially reduced within the last 25 years due to exploitation, fires and forest clearance. The decline is ongoing. In the Sierra Madre this species is an important constituent of the 'yellow pine' forest, where it occurs in pure stands or mixed with several other species of pine, e.g. Pinus arizonica, Pinus leiophylla, and Pinus engelmannii, or in pine-oak forests. This pine is adapted to grow on shallow, rocky soils, but its better stands are found on deeper soils, where it can successfully compete with most other pines. The soils are mostly derived from volcanic rock. At the highest elevation Pinus durangensis occurs with Abies and/or Cupressus lusitanica, at the lowest with Juniperus deppeana and Pinus oocarpa. Other pines are Pinus montezumae, Pinus teocote and in the southern part of its range Pinus ayacahuite can occur with it. In addition this species is associated with Quercus sideroxyla, Quercus rugosa, Pinus ayacahuite and Pseudotsuga (Garcia and Gonzalez 2003). Durango pine is an important timber tree. It grows straight and tall and is (or was) abundant and wide spread in many areas within its range. Logging from natural stands at the current rate is unsustainable and plantations are now being attempted in the state of Durango. The timber is used for construction such as roof beams, general carpentry, furniture, floors, and plywood. This species is virtually unknown in horticulture.
Chia sẻ kinh nghiệm làm đẹp da (p2)
Chào cả nhà, em đã dùng sữa ong chúa được hơn 1 năm và giờ đây em cảm nhận được hiệu quả của sữa ong chúa mang lại. Bằng chứng là trước đây khi chưa dùng sữa ong chúa thì da em bị mụn cám và mụn trứng cá, có cả mụn bọc nữa, da em thuộc da dầu và lỗ chân lông to, nên khi dù dùng các loại kem hay thuốc trị mụn gì cũng không hết. Vì những vấn đề này xuất phát từ nội tiết tố trong cơ thể bị rối loạn, không cân bằng được. Em tìm đủ mọi phương pháp, uống tây, nam gì cũng không giảm được nhiều. Nhưng khi em biết đến sản phẩm sữa ong chúa tươi từ một người bạn, lúc đầu nghe nói e cũng không tin lắm, nhưng cũng tìm hiểu chỗ bán uy tín và đặt về dùng thử xem có hiệu quả không?. Sau khi em sử dụng được một thời gian, có khi em sẽ đắp mặt nạ sữa ong chúa tươi, có khi em sẽ trộn sữa ong chúa với các nguyên liệu tự nhiên khác, ví dụ như mật ong, tinh bột nghệ, bột yến mạch, hay bột trà xanh, nha đam,… mỗi tuần em chỉ đắp mặt nạ sữa ong chúa từ 2 - 3 lần vì da mặt em là da nhạy cảm nên không dám đắp nhiều. Cứ thế em đã kiên trì được một thời gian thì da mặt mình có sự thay đổi rõ ràng, khi soi gương mình không còn thấy mụn nổi nữa mà lỗ chân lông cũng đã nhỏ hơn trước, lượng dầu cũng giảm hẳn. Sáng ngủ dậy, rửa mặt thấy da mình trông trắng hồng và mịn màng nhìn thấy thích lắm. Bây gờ, chỉ cần một chút son là có thế ra đường đi cà phê với bạn bè rồi.
Top 5 Native Water Plants for Your Garden

Agathis borneensis - Borneo kauri, Malayan kauri, Western dammar, Dammar minyak (Malay)
Conservation Status Red List Category & Criteria: Endangered Agathis borneensis has in the past been confused with Agathis dammara, and the 1998 assessment of Agathis dammara treated Agathis borneensis as a synonym. Agathis endertii was also previously considered a good species (Farjon 1998, 2001) and hence assessed separately for the IUCN Red List, however, Farjon (2010) now considers it to be conspecific with Agathis borneensis. Deforestation and targeted logging have been ongoing for many years, have accelerated in recent decades, and are continuing to deplete the global population of this species, especially in Borneo and Sumatera which form the major part of its range. An estimate of 50% reduction between 1950 and 2025 is probably on the conservative side. This puts the species in the category Endangered. Agathis borneensis occurs in lowland to upland tropical rainforest as scattered emergent trees and in low lying kerangas forest on sandy or sometimes peaty soils, where it can form extensive pure stands. This species has been very heavily over-exploited in many areas and as a result its total area of occupancy (AOO) is estimated to have at least been reduced by half and this is still ongoing. Stands covering an estimated total of 30,000 ha discovered in Kalimantan in the 1930s had effectively been logged out by the mid 1960s. Most stands outside the few well protected nature reserves (mostly situated in the Malay Peninsula and in Sabah) have been seriously depleted and it is doubted that regeneration will be sufficient to restore the losses. Habitat degradation has caused further reductions in recruitment of young trees to replace felled ones. This species is one of the most valuable and sought after timber trees in Southeast Asia and it is traded on the international market. This species (and Agathis dammara) are planted on a fairly large scale in forestry plantations in Jawa, but only locally on a small scale within its native range. This species is present in several protected areas, but these only cover a tiny proportion of the global population and are skewed geographically to parts of Malaysia; in Indonesia there are few reserves relevant to this species.
Ait Ben Haddou Kasbah
The ksar, a group of earthen buildings surrounded by high walls, is a traditional pre-Saharan habitat. The houses crowd together within the defensive walls, which are reinforced by corner towers. Ait-Ben-Haddou, in Ouarzazate province, is a striking example of the architecture of southern Morocco. Located in the foothills on the southern slopes of the High Atlas in the Province of Ouarzazate, the site of Ait-Ben-Haddou is the most famous ksar in the Ounila Valley. The Ksar of Aït-Ben-Haddou is a striking example of southern Moroccan architecture. The ksar is a mainly collective grouping of dwellings. Inside the defensive walls which are reinforced by angle towers and pierced with a baffle gate, houses crowd together - some modest, others resembling small urban castles with their high angle towers and upper sections decorated with motifs in clay brick - but there are also buildings and community areas. It is an extraordinary ensemble of buildings offering a complete panorama of pre-Saharan earthen construction techniques. The oldest constructions do not appear to be earlier than the 17th century, although their structure and technique were propagated from a very early period in the valleys of southern Morocco. The site was also one of the many trading posts on the commercial route linking ancient Sudan to Marrakesh by the Dra Valley and the Tizi-n'Telouet Pass. Architecturally, the living quarters form a compact grouping, closed and suspended. The community areas of the ksar include a mosque, a public square, grain threshing areas outside the ramparts, a fortification and a loft at the top of the village, an caravanserai, two cemeteries (Muslim and Jewish) and the Sanctuary of the Saint Sidi Ali or Amer. The Ksar of Ait- Ben-Haddou is a perfect synthesis of earthen architecture of the pre-Saharan regions of Morocco. Criterion (iv): The Ksar of Ait-Ben-Haddou is an eminent example of a ksar in southern Morocco illustrating the main types of earthen constructions that may be observed dating from the 17th century in the valleys of Dra, Todgha, Dadès and Souss. Criterion (v): The Ksar of Ait-Ben-Haddou illustrates the traditional earthen habitat, representing the culture of southern Morocco, which has become vulnerable as a result of irreversible socio-economic and cultural changes Integrity (2009) All the structures comprising the ksar are located within the boundaries of the property and the buffer zone protects its environment. The earthen buildings are very vulnerable due to lack of maintenance and regular repair resulting from the abandonment of the ksar by its inhabitants. The CERKAS (Centre for the conservation and rehabilitation of the architectural heritage of atlas and sub-atlas zones) monitors, with difficulty, respect for the visual integrity of the property. Authenticity (2009) In comparison to other ksour of the region, the Ksar of Ait-Ben-Haddou has preserved its architectural authenticity with regard to configuration and materials. The architectural style is well preserved and the earthen constructions are perfectly adapted to the climatic conditions and are in harmony with the natural and social environment. The large houses in the lower part of the village, with well conserved decorative motifs, are regularly maintained. The construction materials used still remain earth and wood. The inclination to introduce cement has so far been unsuccessful, thanks to the continued monitoring of the «Comité de contrôle des infractions» (Rural Community, Town Planning Division, Urban Agency, CERKAS). Only a few lintels and reinforced concrete escaped its vigilance, but they have been hidden by earthen rendering. Particular attention is also paid to doors and windows giving on to the lanes, to ensure that the wood is not replaced by metal. Protection and management requirements (2009) Protection measures essentially relate to the different laws for the listing of historic monuments and sites, in particular the Law 22-80 concerning Moroccan heritage. The Ksar of Ait-Ben-Haddou currently has a five-year management plan (2007-2012). This management plan is the result of two years of reflection and workshops involving all the persons and institutions concerned with the future of the site, in particular the local populations. The recommendations of this plan are being implemented. Furthermore, two management committees have been established (a local committee and a national one) in which all the parties are represented and cooperate in decision-making. As well as managing the property, CERKAS ensures coordination in the implementation of this management plan. visit our site for more informations...
Qu'est ce que le survivalisme ?
Le survivalisme par définition est un mode de vie qui constitue à une préparation à une éventuelle catastrophe. La préparation des survivants repose principalement sur l'apprentissage des techniques de survie et des concepts médicaux. Avec la bonne préparation, le bon équipement et les bons vêtements avec notre boutique militariat, vous pouvez survivre à la forêt ou prévenir les catastrophes. L'origine du survivalisme a commencé avec l'herbertisme. Il s'agit d'un événement pour former l'officier de marine Georges Hébert. Le but de cette activité est de devenir puissant et utile. Pour ce faire, il est nécessaire de réaliser une éducation sportive, nature et utilitaire. Aux États-Unis dans les années 1960, l'inflation et la dépréciation ont incité les gens à adopter l'idée de kits de sauvetage. À partir des années 1970, certains livres sur le mot « survie » et les méthodes appropriées ont commencé à paraître. Kurt Saxon sera le premier à utiliser le terme "survivaliste". Cependant, John Pugsley publiera "Strategy Alpha" dans les années 1980. Ce livre est devenu une référence pour les survivalistes américains. Dans les années 1990, le mythe du bug du millénaire a donné un nouvel élan au mouvement survivaliste. Les divers événements catastrophiques de 2000 à nos jours continuent d'alimenter la peur et de stimuler la motivation survivaliste. La survie est parfois liée aux croyances religieuses. Être préparé signifie parfois commencer un long voyage avec la famille, les amis et les voisins, mais parfois le voyage doit être commencé seul. Ne pas se préparer, bien ou mal, à l'effondrement imminent, souvent appelé survivalisme. En revanche, il peut y avoir rupture plus ou moins normale. Ils dépendent de l'âge, du sexe, du lieu de résidence, de la formation précédente, des personnes accompagnantes, du matériel disponible... Ainsi, notre magasin survivaliste a pour objectif de regrouper au même endroit du matériel utile et de qualité, et à un prix abordable, dans le respect des grandes règles des survivalistes : eau, alimentation, énergie, hygiène/santé, défense, et blog Connaissances. Par conséquent, nous ne parlerons pas d'invasion extraterrestre...
