Abstract: The present study focused on the plant species consumed by Ibex in Khunjerab National
Park (KNP). Among which the most palatable grass Saccharum ravennae L. was collected from KNP,
Sost and Gilgit to analyze protein, carbohydrate, amino acids, and crude oil. The data about the plant
species consumed by Ibex was collected through simple questionnaires and direct interviews from the
shepherds, KNP staff and local inhabitants. A total of 17 plant species belonging to 15 families were
being consumed by Himalayan ibex in KNP. All families having one species each, except Asteraceae
which have three species. Saccharum ravennae is one of the most palatable grasses establishes itself by
growing on harsh substrates like gravel, cliff and stream banks and is much taller than the surrounding
vegetation. The oven dried shoots of all samples were analyzed for the qualitative detection of proteins,
carbohydrates, amino acids, and crude oil. These three samples of Saccharum ravennae collected from
three different elevation and topographic areas contained carbohydrates and crude oil, whereas proteins
and amino acids were found to be absent. To improve the productivity and forage utilization, it is
necessary to have knowledge of nutritive value of range species and their germination under harsh
conditions. In-situ and Ex-situ conservation of the important plant species is recommended as most of
the highly palatable plant species are rapidly declining due to anthropogenic and climate change
pressures and also due to high intra-specific and inter-specific completion among wildlife and livestock
species for forage. Previously, there was no research focused on chemical analysis and nutritive value
of Saccharum ravennae.

1. Introduction
Khunjerab National Park (KNP) is the one of the
high altitude parks in the world and is a habitat of
many wildlife species especially the Himalayan ibex
with abundant population size due the available food
for their consumption. This park has unique and rare
plant species due to its unique climatic and
topographical features. Among all the plants found in
KNP, 27% and 39% were found to be highly palatable
and palatable (Shedayi et al., 2016).
Saccharum ravennae is among one of the most
palatable plant species consumed by ibex in the
Karakoram mountain ranges. Saccharum ravennae L.
commonly known as Ravenna grass established itself
in KNP with relatively more disturbed by natural
disasters. It produces copious biomass, especially by
growing on harsh substrates like gravel banks, and
being much taller than the surrounding vegetation. It
can anchor soils and act as a physical barrier to stream
flow through its biomass and accumulation of flotsam,
thatch and sediment. This may shift erosion locations
(Carlson, 2009).Removal of soil moisture and
nutrients by Ravenna grass roots is also possible
competitive impact that may be harmful to native
seedling growth and health for established native plants
(Warner et al., 2003). The most important factors
affecting forage quality include forage species,
maturity and fertilization (Arthington and Brown,
2002).
Screening of high yielding perennial grasses of
enhanced nutritional worth is essential for improving
the ruminant animal productivity in range areas. It has
been documented that with advancing age, the
percentage of crude protein and non-structural
carbohydrate contents decreased while the dry matter
(DM) and cell wall contents increased in all range
forages. From the aspect of animal feed quality, protein
which is obtained from the stem is of much lower
quality in relation to that provided by leaves
partitioned in higher percentages (Stanisavljevic et al.,
