The common myna is a songbird belonging to the starling family (Sturnidae) that reached Israel as an exotic bird and escaped from the “Tzapari” in Tel Aviv in 1997. The myna is an invasive bird in many countries around the world, and has been declared one of the 100 most globally destructive invasi...

Much evidence from recent years indicates that populations of flying insects in general and bees in particular are declining significantly. A German study reported a 75% decrease in the total biomass of flying insects between 1990 and 2015. The reasons for this worrying phenomenon are not clear, but it appears that the bee crisis stems from a combi...

The little fire ant is a tiny, red ant, active day and night, which stings humans and their pets and displaces other arthropods. It causes severe harm to the ecosystem and constitutes a severe hazard to humans. In 2018, the little fire ant reached Ramat Hanadiv and spread rapidly throughout the Memorial Gardens, impacting significantly on local art...

The study focuses on the effects of cattle grazing on the reptile community in Mediterranean woodlands in northern Israel, through the changes in vegetation structure and the presence of the cattle egret (Bubulcus ibis), a predator that accompanies cattle in the field. The study sheds light on the role of...

In the ancient Jewish texts it is considered to lack both taste and smell, but it seems that some find the willow to be both tasty and nutritious, and if this is not enough, it fulfils a central role in an innovative Israeli-Jordanian study

Reptiles are one of the more susceptible groups to suffer from biodiversity loss as a result of human-induced changes in the environment, such as global climate change. There is solid evidence for the influence of global warming on species biology such as range-boundary changes and phenological shifts

Regeneration and mortality of woody species in the Mediterranean landscape - Effect of interface treatments, competition and environmental conditions.

Ozone is the most prevalent and damaging air pollutant to affect natural vegetation, forests and crops (Global economic loss associated with ozone damage to crops is currently estimated to be $11-26 billion annually; Mills and Harmens, 2011). During the industrial age, anthropogenic emissions of fossil fuel have acted to approximately double the gl...

The invasion of pine (Pinus Halepensis) to the Mediterranean scrubland and natural woodland, changes the composition and height of the vegetation. These changes may alter the movement of predators and thus increase predation pressure on prey.

The mountain gazelle (Gazella gazella) and the chukar partridge (Alectoris chukar) are used as bio-indicators sensitive to changes in the composition of their shrubby (garrigue) environment and the landscape

Yagil Osem, Volcani Center and the Weizmann Institute
The study deals with how the rainfall regime dictates the structure, function, and stability of natural and man-made ecosystems in Israel and the applied implications for management in changing climatic conditions.

Road collisions involving animals and vehicles (wildlife-vehicle-collisions; WVC) affect wildlife individuals, populations, and ecosystems. At the same time, they cause economic damage and sometimes even human fatalities.

Throughout the world and in Israel, the question has arisen as to whether climate change and global warming are affecting the timing of growth, flowering, and fruit ripening in plants. These changes can impact the entire ecosystem, for example – the impact on sources of food for insects and birds.

In recent years, massive dehydration of oak trees was observed in Ramat Hanadiv. Oaks (Quercus calliprinos) grow only at a few suitable sites in the park

Vineyards around the world are important foraging sites for insectivorous bats (insect-eating bats), for whom moths, which are vineyard pests, are an important dietary component. Most species of bats in Israel are insectivorous, feeding on an enormous quantity of insects at night.

Mountain biking is a popular and fast-growing activity worldwide, but compared to other recreational activities, there is a relative dearth of understanding and scientific studies on its ecological impacts.

The Mediterranean fruit fly (Medfly) is a highly significant pest of deciduous and citrus crops, and much effort is invested in its control. In order to improve control efficacy and minimize pesticides' use, a large scale regional integrated pest management project is carried out in Hanadiv valley during the recent years.

A unique study was conducted recently  at Ramat Hanadiv Memorial Gardens and Nature Park, with collaboration between the research division, the public and Ramat Hanadiv Nature Park, and the Department of Geography at the Mt. Scopus campus of The Hebrew University.

The Southern Carmel ridge is composed mainly of hard layered limestone and dolomite. It was created initially by folding movements and later on by faults and tectonic activity. The Carmel Mountain as well as its surrounding area was then raised and exposed to erosion. Erosion is still taking place today.

Ramat Hanadiv is located at the southern end of Mount Carmel, south of Zikhron Ya’acov, at an elevation of about 120 metres above sea level. The edge of the Southern Carmel, which is mainly composed of hard, stratified rock, is positioned above the coastal plane, in contrast to the mild topography of its surroundings.

Global climate change predictions for the Mediterranean regions forecast a rise in temperatures (4°-5° in summer, 2°-3° in winter), a decrease in the quantity of rainfall (up to 20%) and a serious increase in drought frequency (IPCC 2007, 2080). As access to water becomes scarce, a deceleration in tree growth is expected as well as the death of tre...

The soil survey of Ramat Hanadiv aims to provide detailed information on the characteristics of the various soil units found in the area, to map the spatial distribution of each soil type and to propose recommendations for future land-use and development policy.
