English title: Duration and age class distribution of some meadow grasses in the young age.

The data has been collected from an old natural meadow in Sortavala, Karelia (on that time it was part of Finland). The vegetation on that meadow was very homogenous. All plants of the selected species (Trollius europaeus; Ranunculus auricomus; R. acer; Potentilla erecta; Alchemilla vulgaris; Geum rivale; Prunella vulgaris; Chrysanthemum leucanthemum; Polygonum viviparum) were collected from the sample plots with their roots. The seedlings were then ordered into age classes, and the shortest possible time before inflorescence was determined. To find out the germination time sowing trials were conducted.

The seedlings are very abundant in the youngest age classes and then the amount of plant individuals sinks quickly. The reasons for dying are e.g. insufficient amount of nutrients available and the lack of winter hardiness.

English title: European white elm (Ulmus laevis Pall.) in the region of Vanajavesi-lake.

The article describes the distribution of the European white elm; its sites and vegetation communes; phenotype (size and form); variations in the leaves; inflorescence and fruiting; germinative capacity of the seeds; regeneration, both vegetative propagation and from seeds; commercial use of the timber; and the history of European white elm.

English title: On half-deciduous woodlands in Estonia.

Half-deciduous woodlands are the combination of deciduous forests and heath forests from their vegetation. The article describes three half-deciduous forest types from the commune of Hager, 40 kilometers south form Tallinn.

The occurrence of half-deciduous forests depends on the soil conditions, especially on lime content of the soil, when the occurrence of other forest types is more a question of climate. They are important as an original site for many continental plant species.

K. Linkola. (1929). Zur Kenntnis der Waldtypen Eestis. Acta Forestalia Fennica vol. 34 no. 40 article id 7253. https://doi.org/10.14214/aff.7253
English title: Knowledge on the forest types in Estonia.

The article summarizes the observations about forest types from different parts of Estonia. The chosen examples represent the normal forest where age class division is natural and the species composition has not been altered through felling or grazing. These are mainly found in the areas of earlier manors of the nobility. The samples are only from mineral soils. Vegetation analysis and middle-European height-over-age-survey were made.

Because of the great share of herb-rich-forest the forest type classification for Estonia is complex. There are many types that have not been described earlier.

The study describes the characteristics and the vegetation types of the heath forests, fresh forests, half-herb-rich-forests and herb-rich-forests.        

The volume 34 of Acta Forestalia Fennica is a jubileum publication of professor Aimo Kaarlo Cajander.

English title: Distribution of the agricultural settlements on different forest soils in Finland.

The paper studies the relationship of settlements to the forest types and forest soil. The observations have been done and data collected in southern Finland, around lakes Päijänne and Saimaa during summer 1917. Because of the shortcomings in the data, the results in the paper can be seen only as indicative.

The settlements have spread out firstly to areas of grove alike soils and herb-rich forests. The human settlements are still on these days concentrated on those areas. When more land is needed for agricultural purposes, the more fertile areas were introduced first. With forest type classification this means moving from herb-rich Oxalis-Myrtillus-type to Pyrola-type and to some extent Myrtillus-type. The more barren types are used as fields only very seldom. The differences in the fertility of the soils affects strongly the welfare and development of the people and the communes. 

The study shows that when considering the soil and vegetation, preconditions for agriculture are very different in different part of Finland. Also the climate and the geographical characters vary. To win more agricultural land, the fertile peatlands should be considered.
