Research journals likeJRMEplay key roles through the publication of peerreviewed research, and it is through such publications that the field has the potential to grow. The metaphor of a growing tree is a useful one to explore in the context of mathematics education research. Growth in the natural world is generally multidimensional. A tree's growth is measured not only in terms of its height but also in terms of the girth of its trunk, the spread of its branches, and the development of a substantial root system, all of which are essential for the tree's continued growth and survival. Soil nutrients need to be replenished, and without sufficient moisture, growth is arrested, and the tree becomes stunted. Many of the most interesting natural landscapes include a range of tree species as well as supporting undergrowth.

This paper approaches an issue of real importance, namely the sea-buckthorn influence on the areas attacked by erosion. We consider that this effect is mainly a result of its extremely developed root system, as well as of the nodosities formation on the roots. The study was conducted over a period of 3 years (2011-2013) in two landslides areas from Prahova and Dambovita counties, from where were collected 5 plants (from each area) in 3 repetitions. Calculating the averages regarding the plant roots depth, but also the number of root suckers and nodosities, can be easily deduced the role of these plants in soil fixation, hence their eco-restoration value.
