The arboretum consists of a living collection of indigenous and foreign tree species that can thrive in the specific climate. For example, it can be used to demonstrate tree species in a general way or to study the biological characteristics of naturally occurring trees or their natural groups, as well as the introduction of exotic tree species, ecotypes, geographical variants, etc., and how they acclimate, propagate, or hybridize. It can be set up as tiny stands of the same species or as a park arrangement, which highlights the trees' aesthetic value. Planting is carried out based on systematic, ecological, or geographic relatedness. In France, the world's first arboretum was founded in the 17th century.
Trees cover about 30% of our planet. They produce oxygen that we need for life and absorb carbon dioxide that we exhale. One mature deciduous tree can produce enough oxygen to sustain 10 people for an entire year.
Trees form forests, which can also influence regional weather and create their own microclimate.
They help absorb excess moisture, reduce soil loss, aid in erosion control, and slow down water flow, thus preventing floods.
Groups of trees can also serve as windbreaks, providing support for wind-sensitive crops.
The network of roots can stabilize large amounts of soil and prepare the foundation of the entire ecosystem against erosion by wind or water.
Trees can capture pollutants in the air, such as carbon monoxide, sulfur dioxide, and nitrogen dioxide. They can absorb various toxins from the soil, and this unique ability is especially important in areas with sewage or water runoff.
Trees are natural noise barriers. Noise is mitigated because in forests, leaves rustle, herbs whisper, and birdsong is also important. A few well-placed trees can reduce background noise by 5 to 10 decibels, or about 50% for the human ear.
Trees or shrubs provide food for people and animals, including fruit, nuts, seeds, and sap, but they also allow mushrooms, wild berries, and beetles to grow in forest soil, which are then consumed in the food chain by birds, rabbits, fish, and wildlife.
Trees and other plants living among them can heal us. Many medicines contain medicinal plant ingredients.
Paper is made from trees, furniture is made from wood, and wood is a fundamental building material.
Trees create healing energy, making a walk in the forest an important element of relaxation. Our overall health, body resilience, and lifespan depend on the quality of the atmosphere. Air saturated with negative ions, which are vital for our health, is found in natural environments such as forests, waterfalls, lakes, and after a storm. Without trees, neither humans nor animals would exist.
The area of the Arborétum Doľany covers 2.5 hectares and hosts 59 species of trees. The tour begins at the national landmark "The Parish Church of St. Catherine", where a large information board about the arboretum and the protected bird area is located. The entire route is approximately 822 meters long.
The entire area of the arboretum is monitored.

Within the Arboretum Doľany, there is a rare lime tree estimated to be 400 to 500 years old. We will not determine its exact age, as it would have to be cut down. It is located near the church of St. Leonard.
The layers of rocks on which this linden tree grows are only found in the vicinity of Dolian, hence they are called Dolianske. They consist of conglomerates breccias, as well as sand and gravel. The base of the conglomerates is made up of limestone gravels bound by a calcareous cement, which, after being dripped with diluted HCl bubbles significantly (CO2 escapes). Breccias, on the other hand, consist of angular fragments of dolomite, which, unlike limestone, contains more magnesium. The Dolianske layers were formed in a sea that was present in the area of today's Danubian Lowland during the younger Tertiary about 14 million years ago. The bay extended into the Little Carpathians, which provided it with material similar to today's alluvial cone. The cave behind St. Leonard's chapel is classified as a pseudokarst cave. It was formed by mechanical disruption of rocks along fractures or faults. The chapel dates back to the 14th or 15th century and is built in the Gothic style. A peculiar feature of the chapel is that its left side is embedded in the rock massif, forming the right part of the structure. Inside there is a recessed rock from which water slowly drips, which the locals collect with the idea that applying it to the eyes helps.
